Community Insight:
We used to love this game so much but its no longer available.
We are learning to "sight read" piano music. It requires reading both bass and treble clef notation simultaneously. We think this game must have been made with that in mind. We have had a noticeable improvement and we're not that really that good at the game yet.
We see a lot of reviews saying that ads pop up in the middle of the game, but so far the only ads we've gotten have been at the exact time that we died. This probably confused people into thinking that the ad caused their loss. The only problem we have had so far has been that we're color blind.
Way Way to many adds and they pop up right we the middle of the game you could of just made the app cost money instead. So bottom line they should pay use money to play this app.
This is a really fun game, but when we're on a roll and winning everything, an ad pops up and makes us loose. You seriously need to fix that. But you should also put more little mini games.
We really enjoy this hard game.
Helps improve our coordination and multi tasking, even though multi tasking is technically proven impossible.
So much fun. Great brain training.
But we are losing because we know nothing about mathematics:( Thanks for the game.
This game is great. Wish it had difficulty settings and that you could pick different soundtracks. The music is good but it gets OLD! Good work y'all.
The concept is fun and challenging, our only issue is that ads tend to pop up mid game. We would purchase however we have yet to be able to play a full game without an ad interrupting.
Great little game. Innovative, at least as far as we know. Keeps you in your toes.
Very fun game! Just wish we could turn off the music and leave the sound effects on.
This is a great game, one of 5 of its type (split screen simultaneous mini games) we've downloaded and BY FAR the best; it's a wonderful brain workout that we use to help sharpen our focus, attention, and observational skills. There's a nice variety of games at the perfect difficulty level, and the game/graphics work well on our old iPad mini (1) with iOS 9.3. We would definitely award it 5 stars except for, as everyone else says, THE FRICKIN' POP UP AD THAT INTERRUPTS GAME PLAY. We've never seen such an intrusive ad in any app, ever; it pops up every COUPLE MINUTES, often in the middle of game play and closing it frequently causes us to lose one or both mini challenges. This is TERRIBLE and at this point we're unsure if we'll continue to play this game or not. If the problem is fixed we will change our rating to 5 stars and download anything else offered by this developer. We have little hope though since it's already been years. **NOTE: one reviewer suggested playing in airplane mode; this does NOT work to avoid the pop-up. :(.
Yes. Yes, there is. And it's annoying as heck. Like everyone else, we HATE how an ad shows up in the middle of a game! It would've been fine if it was at the start screen, but NOT in the middle! We instantly lose, bc the frigging "x" takes a while to load! We love this app, but right now, we don't. And NO, we're not going to fall for that cheap trick to press that "remove ads" button. Until they fix this, we're deleting this. Thank you.
We LOVE this game! But theres some glitch where once we die, an ad jumps up, then we are booted out of the app. When we reopen, it's like its opening for the first time. If you guys could take another look at this one, we'd really appreciate it. It probably just needs to be updated to fit this iOS, or for the newer phones or something. Thx for making a really fun game.

It used to be a really fun game till the update came with the ads. We understand ads, but these are the ridiculous ones where they hit you and accidentally get clicked to the store. You used to be cool, but we've moved on. Buyyyyeeee.
If you asked us what to give this app five months ago, we would've said 5 stars. But, after signing into Game Center and trying to play it, we have major issues with the app itself. The first issue is the advertisement that always pops up when we're trying to play. It directly asks "Do you want to try our new game. 2F1B? It's absolutely free!" with a 'Get It Now' and 'Miss Out' option. Although the ad itself is fine, we don't think it's appropriate to put them up in the middle of the game, which prevents the player from clicking on the two mini screens. We even got one we couldn't click away, because the bottom half was off the screen. Our second issue is how, after four months of not playing this game, there still isn't a new game mode, or even a new mini game. We're starting to think that there will never be any, and these same games get more annoying and boring by the minute. If you address both of these issues, we will gladly return our rating to five stars.
This game is awesome and we really enjoy it, but it doesn't work with iOS 11. Can you please update it so we can keep playing? Thanks.
The ads would pop up right in the middle of the game. You click out of it and bam, game done. Deleted game. Not worth it.
Every 30 seconds an app interrupting ad.
How can we play with all of those stupid advertisements.
We love this game but it keeps crashing please fix.
This game is great. We like it, but the ads pop up in the middle of the screen when playing. Fix that please and we will come back to play. Also, we keep getting daily reminders to come back and play. It is real annoying. We have been to the settings and there is nothing there to turn off the push notifications. Annoying.
We try to launch it and it lies dormant.
The app was horrible it kept in crashing and it kept asking a stupid question before it did crash.
Super fun continuous play! No waiting for your turn.
Great game it is fun an we like it because it is great and we like it because there are to screens so we like it cuz of that and we like it Ecuador it is fun and we like it because we like writing reviews on fun games we like because we like them because they are very fun and we like this game because of all of the fun mini games and using two fingers and one brain because we like it cuz of that.
Challenging game apsolutely fantastic.
The game is fun but it lags out when other apps are streaming like itunes.
It's a cool game and all, but they definitely shove adds down your throat. Which is fine, because it's a free game and all. The only issue is that we have an iPod touch and am unable to play when we do not have an Internet connection. This is because when the adds try to load, they are unable to and the game decides to continue to wait for it to load.
It would be a good game if the adds didn't pop up every few seconds during gameplay. It got very obnoxious after the first game.
We're 70. Guess we are too old to do two things at once. We can do one side or the other but not both at the same time, though we type with two fingers on our tablet!! ;).
Starts playing sound at game start even when sound setting is turned off.
The app crashes when closing the full screen ad… Latest firmware iPhone5C.
We got this game when we were going on vacation and would was going to need some good offline games to pass the time on the plane and have been hooked since. 2F1B is original and fun and challenging all at the same time.
It's great you have to be smart to play.
It's so challenging and it hurts our brain. So much fun.
We don't usually rate games, but this game is absolutely awesome! We use it to wake our brain up in the morning. It's always different and never boring. A definite 5/5 from us.
Very challenging and great at making you force quick decisions… We've seen nothing like it.
Not only is it a fun and challenging game, it is a great game to get if you thinking about band or an instrument!!! When you do band or an instrument you have to look at a music sheet while playing the instrument so you must use both sides of the brain.
This game is ridiculously addicting. We've showed it to our father and he too is now addicted. This is a game you must download.
One of our favorite games. Very challenging – we imagine kids would get easily frustrated because it is very hard.
We love this game and play it all the time,but the commercials are ridiculous and pop up all the time.Worse is,you can't click out of them until the commercials until the advertisement us over! We love this game over all though.
It's had some odd times, and some bugs, but it's held up. For a free app you have to try it. Is a great brain breaker.
We love this game. 2 games at once is incredible, the more you play the more you enjoy it. We just want to get the red button that turns green problem fixed some we can start breaking some records out here. We're sure the folks are on it, but if not we wanted to add our two sense. Gratzi.
There's ads during the game throws you off by 100% and makes you loose a life game thingy lol Please fix that bug, its frustrating :( Otherwise, Great game! :).
This game is hard to grasp as first but after a few rounds you'll like it, and we find the game addicting. The only downside at the moment is after you get two a certain point, the puzzle where you have to touch the button when it turns green will automatically fail you immediately when it turns green, and you cannot react to it. Other than that, it's a fun game.
Good game. Only issue is like most, the green button as soon as it turns green will fail you. Also noticed that a few of the helicopter survival ones literally cannot be passed – every lane has a ship coming at same speed. That one has only happened a few times but that green button needs fixing pronto.
