Radiant Grid – Puzzle Game Review
Radiant Grid is a Puzzle game from Open Planet Software Limited, first launched in 21st April 2016.
It’s rated 4+ and currently has 14+ ratings on the App Store.
What Makes Radiant Grid Stand Out
Start at the origin and tap the squares to light a path across the grid. There’s just one rule! The numbers scattered across the grid tell you how many squares you must light up around each one to solve the puzzle… and that’s where the skill comes in! One mistake can lead you down the wrong path!
"This is quite simply one of the most beautiful puzzle games I have ever played. The design is simple, yet aesthetically pleasing, and the soundtrack is a wonderful sonic wash that perfectly compliments the gameplay. The puzzles themselves are well pitched. The introductory rounds are small enough to lend themselves to both a studied approach or random tapping. They gradually ramp up the difficulty level, and with so many to work through, there is great value for money to be had. Now, off to the iTunes music store to buy the soundtrack…" – an App Store customer from the UK.

Community Insight:
We hadn't played for a couple of weeks and when we launched the app today, we were back at the start. Looking in the app store it shows that it was updated a week ago and, with that, all of our progress was wiped clean. Not cool. Shame on you for this gross oversight.
Beautiful game. Simple pleasant. Difficult. If you cant figure out the rules you are a nincompoop, dont leave reviews of your own cluelessness.
Devise a route from the source to the specified endpoints, respecting constraints. Very satisfying. Visually appealing.
Fells like an active engagement puzzle rather than some game designed to make you buy crap to actually make progress. IMHO if you dislike this game because of its unclear rules then you must hate a challenge. We feel like it teaches how to learn how to play rather than outright teaching how to play, which builds intuition youll need the farther the game progresses.
Enjoyed very much! Was bummed when we completed the master rank and was no more :(. Need more to solve!!! It took us several weeks on and off to accomplish the very last one though. We were stuck on number eight. Anyway fun to figure out for sure.
Most games today start off with a bunch of annoying prompts telling you how to play. This one had a little text to guide you in the first level, but it wasnt enough to not let you figure out how the game works on your own. It reminds us of playing old games growing up where you put the cartridge in, turn it on, and then youre just there in the game and you have no clue what any of the sprites are supposed to be or what kinds of puzzles might be in the game. All you know is that you want to beat the game. Initially we thought that the numbers corresponded to each square, and it was saying how many paths that square needed to the source block. Then we thought it was saying how many lines around the outside of the filled blocks touched that corner. It wasnt until around Level 2, puzzle 3-ish that we realized how it really worked (we wont spoil it here). We kind of accidentally stumbled into playing this game without reading anything about what it was. We downloaded one of Open Planets other apps, and saw their bundle being shown next to it. The other app in the bundle (not this one or the one we had originally bought) looked like something Id use, so we bought the bundle. Then today, we saw this app that was also included on our home screen so we tapped on it, and it was a fun little mystery to solve. We tapped on it, and then we saw Game Center open, so we knew it was a game, and then we started trying to figure out what the numbers really meant, which kept us interested until the puzzles got hard enough to be interesting in and of themselves.
There is a tutorial mode to teach you the basics of the game — put down connection squares that touch the number shown on the paper. Only n squares can surround the number. So complex layouts can be tricky and fun. Easy to come in and start playing and come back later for more.
There is no instructions. No bueno guys.
