What Makes Astonishing Baseball 21 Stand Out

Astonishing Baseball is your daily dose of baseball management on your smartphone or tablet, and for free, with no ads. Become the manager of an astonishing sports team full of stars, and as the GM, lead your players to the ultimate reward: the Baseball Cup!

Astonishing Baseball is not your usual baseball simulation game. It's not only about tables full of players and stats. It's not just trading players and signing free agents. In Astonishing Baseball, you're writing your own story with one goal in mind: win the Baseball Cup. And for that, you'll need all kind of skills.

*A living world
Astonishing Baseball features an artificial but living world. Fans are posting about the game and your brand new rookie. Journalists write articles about your starter's last night performance and interview you. Players send you messages about their concerns, their contract… Or maybe they're inviting you for dinner! It's all about baseball!

*The lineup of your dreams
Astonishing Baseball allows you to create the team you've always dreamed of. Make trades with the greedy other teams of the league, or sign free agents during the offseason. Draft talented prospects and train them to the rank of baseball stars during the Legends Contest. You're the coach!

For baseball fans and stats nerds
Astonishing Baseball is very easy to learn. If you know the game rules, you'll know how to play! But if you're a sabermetrics savant, you'll find all kind of stats to satisfy your nerdy instinct! And in AB21, we've added some niceties, like charts and WAR projections!

*Play on your own terms
Astonishing Baseball can be played offline, as much as you want. You don't need to wait between games. You don't need a data connection or Wi-Fi to save a game result. You don't need to create an account to build your team. You don't even have to pay. Just play now! Seriously, just tap that download button and enjoy it!

*Get international
Not enough talent in your league? Send your incredible and local scouts to find the best prospects in the world, and then invite the most promising player to your team! But be careful, even the best scouts can make mistakes…

*A Prodigious Story
Create your own player and follow his adventures through high school and college. Will he join the Emerald University of Seattle, or travel to Japan to study baseball? Can he find love, and keep his best friend close while becoming a local superstar? Is that legendary Cap of Neva really worth it? Play through dozens of events and storylines until your young prodigy joins your team!

*A fierce online competition
Even if the entire solo mode can be played offline, you can also decide to play online anytime, and participate in one of our many multiplayer modes! Try to become the King of Baseball in the Astonishing Contest, or conquer the title of World Champion. Except if you want to play with friends, and go on a road trip with your guild to conquer cities!

*A Tremendous Rivalry
Maybe you're going to have success with your team, but at the top of your fame, a talented coach might come to steal your throne! Will you be good enough to get him out of this league? But beware, because the Dargor family is ready to sabotage you. And Regis might not be your worst enemy in this…

*Live incredible stories
As a coach, you do have a life too! In Astonishing Baseball, you can take your team to a burger restaurant, help local associations, but also meet your favorite author, become a rock star and even marry the love of your life!

*New challenges await you
In AB21, you can now play one of our many scenarios! Go back in time to manage the famous 1927 superstars, or try to rebuild Detroit in extreme mode!

Player Experience Highlights

Community Insight:

We think this game is amazing, nothing is blocked behind a paywall (even though you can buy extra TP or $$). Challenging and fun. Our only item of improvement is possibly making a way to be able to check your scouted International Prospects in the offseason so that you can adjust your roster accordingly with free agents in the offseason.


If you love sports strategy and simulation this game is for you. The UI is amazing and super immersive for such a simple game. Custom teams and players, trades, free agents, college recruiting, stadium upgrades, you name it. Hands down one of our all time favorites. Best of all its not pay to play.


We love this game! The only things we would suggest are: – Ways to improve non-rookie players, like sending them to the Minors. – Be more interactive with players. Yknow, develop some kind of relationship, being able to push them to try harder. Something of that sort.


It is a very in depth and fun, Exciting baseball game with a very alive world.Keep up the good work.


We enjoy this game, we think the draft could be a little longer, maybe in the 5-7 round range. But good game.


The lineup system is to confusing because it can change into a puzzle some times.Also can you have a setting to turn off automatic pitching change because it gets annoying sometimes.


We like the game overall. It's fun to sit and waste an hour or two on. A few things we think need tweaking: 1. Budget – Overall budget for players should be one pool to do with what you want, not separated so we can't sign anyone. 2. Trading – Takes into account performance only and not a multitude of things like IRL trades do. 3. Training Points – we like training points…for training players, scouts, and coaches. However they should not be used to hire coaches, scouts, and a chef. That should be taken care of with budget money. There simply isn't enough training points to go around. 4. Developer Attitude – Talked with the person in the Discord server. They weren't rude about anything, but they didn't listen to any feedback we tried to give. They brushed it off with the excuse "it is how it is". We see great potential for this game to be a free alternative to OOTP, but unless the dev is willing to listen then it's not gonna go anywhere anytime soon.


Easily the most fun and addicting GM simulation game/ franchise Ive ever played, we play them all! Please keep the updates coming.


We can never win closer of the year even tho our pitchers have the better stats lol.


This game is very very addicting. We like how it has a simple you ui and also has fake teams but semi real players. All they really did was change the name of the teams change one or two letters in the player names, you can tell who they are. The reason Im leaving five stars is because this is basically MLB the show level franchise except there is no minor-league trading so you cannot trade from a minor league player. That is also one problem but its not a big one due to the fact that the game is so much more options to get player such a free agents trade in the draft . One problem that does bother us but still wont hinder us from leaving five stars is that when youDraft a player you dont automatically get them for five yearsWhich is the maximum years you can sign a player to.


Game is fun but it can be very stupid sometimes. We can have like 5 4 star players vs a team who is 10th in their division, and lose by 3 runs. Like its kind of dumb that the worst team can come back from a 4-1 lead. Plz fix.


We know it's got a lot of reviews but we hadn't seen it get a lot of advertisement in the store. We're so glad we found it because now we can't stop. If you like a simulation sports game this is as close to perfect as you'll find here.


We think the games really good. But we hate how hard it is. There should be some difficulty modes, Hard easy medium etc.


So far this game feels fun and we havent even played a game.


Favorite baseball game Ive ever played Ive put to much time in it and when we needed help with something the devs responded extremely fast highly recommend.


The games random outcomes make no sense depending on your team players and its also rigged and unfair in the rivalry because ur rival after a while has a team of all legend players and always beats you except maybe 1 out of 20 times. This is just ridiculous.


Really addicting, fun game. Highly recommended.


Just needs more depth/options/customization and it would be 20 out of 5.


Im not joking this game is by far the best baseball simulator out because of how addictive it is, they have hall of fame where the best of the best players in that league is/was, we never knew this until now that They have The Best player of all time award ever 25 years. Even tho Ive had games by this creator for a Long time, years more likely we love this game so much, the only problem is they put players from teams that did worse than our player on our team in the hall of fame, no one with less than .290 for their batting average and less than 250 home runs and one award, minimum 3 awards should be in there but everthing is great Easy 5 stars if we could we would put a 6 star rating.


We dont do reviews on games but this game is by far our favorite baseball game.


Love the depth. Its a good game for baseball lovers.


Excellent bones, this game could really be great, but there are a few issues that really have to be fixed if the game could ever hold our attention long term. Everyone mentions the layout and button placement not being optimized for current iPhones with a notch, and yeah its kind of crazy that its so bad, but its not game breaking . What bothers us more is the fact that if the CPU loads the bases against us and we bring in a reliever, any ensuing runs get charged to the reliever we brought in. Another big one is that your bench players never play at all if you do not manually substitute them in; maybe Im missing a setting somewhere for this? We would also love it if you could actually have player ratings beyond the star system that only appears as you train players, which is another issue; the training points are way too slow and tedious to accrue imo. We have no idea how to judge players without stars beyond their immediate/current stats. We would also like to see players progress on their own throughout the season without training, and the option to include players in the minors in trades. Also, its absurd to not have a baseline budget capable to hiring coaches lol, we just dont get that part of it, the grind to actually gain ground is just a bit too much for us overall. We know thats a long list but the game is still fun if you enjoy GM games.


The best app for running a team with game play that we have been able to find.


Have been playing for about a week and its pretty fun so far.


A good sports management game requires too things randomness and allowing the player to put the right pieces together this game has both and it also balances both very well it never has gotten dull or boring because your not consistently winning and when you finish your first game you have numerous scenarios and many online ranks to climb 10/10.


Amazing game, in depth gameplay and somewhat realistic scenarios and outcomes, however, we do have one complaint/warning, the games difficulty setting cannot be changed after you make one, so if you make a game on easy difficulty and want to raise it you cannot raise it in that game, and same vise versa.


Ive just begun playing but finding the game entertaining and to be a nice break to the day, and also before bed. We dip in and out, get a game or two played and learn a little more each day.


Like we could get a 50 game win streak than get a 10 game losing streak and lose in the 1st round of the playoffs.


Gets you sucked in really fast once u get the hang of it.


Great game! Love how in depth the game is! The customization is fantastic. We also love the statistics involved.


Its fun but a lot of things could be better.


Could you guys add a coach mode where you can change teams and all that because it would be to cool to be able to do that and mix it up every once in a while and maybe it could be an offline mode only as to not affect the online modes there already.


This game is really great if youre a baseball fanatic! One bug Ive seen is that if you change team names in the league, the news section and stadium section wont update to match, so youll have outdated team names throughout the app. Thats a bit annoying, and we hope the devs address it soon.


Ive enjoyed playing this games so much.


This game literally has incredible potential but its got two major problems. First, you have to fix the placement of the buttons. Theyre on the top and bottom but very close to the edge so theyre very hard to press. Secondly, you have to make it so that we can trade draft picks. You fix these two problems and it will literally be perfect. Incredible potential.


Unfortunately, the poor UI locations of buttons on the iPhone Max prevent us from enjoying the game. The notch is not handled, and buttons in the top or bottom corners of the screen are very difficult to press. This make the game very tedious to progress through the menus. OTHERWISE, GREAT GAME! Best baseball manager on the apple store and we love the perfect mix of simplicity and depth that allow the game to be fun, challenging, and easy to progress through many seasons (Please allow us to play and fast forward through a game with a single button!) Thanks for all of your hard work developing this game, and as UI fixes come we will gladly update our review.


People have talked about the fact that some of the icons go under the bezel but the way that selection is set you can accidentally screw yourself over really bad and there needs to be a fix for that Ill be deleting this game until they provide that fix.


We love this game Ive never had so much fun ever since our ps4 stopped working we feel like this game can be something big so maybe add a soccer version of astonishing even with astonishing basketball and football they have been so fun to play and the only thing that can make it better is if you had like a soccer or hockey version of this.


Great baseball game, if you like sports sims games this a good way to go.


A few features from the old game are missing, like one of our favorites, trading draft picks. Other than that the best game Ive ever played on our phone.


There is a strong idea here, but the UI is poorly placed, and on an iPhone 11 Pro Max, things get cut off in the notch and bottom of the display. The sim engine is decent but nowhere near ootp, which this claims to be similar to since we searched ootp baseball in the App Store and this came up.


Not sure how this game doesnt have billions of downloads. Any baseball fan, heck, any sports fan would love this game. A must.
