Radiant Grid 4+

The Minimalist Brain Teaser

Open Planet Software

    • $1.99


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.

Radiant Grid is an immersive, minimalist puzzle game with a soothing, ambient soundtrack.

99 increasingly challenging, handcrafted puzzles.

A simple concept that will give you hours of relaxing game play.

** Soundtrack now available on iTunes and Apple Music **

Makes you think!

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. I feel like it teaches how to learn how to play rather than outright teaching how to play, which builds intuition you’ll need the farther the game progresses!

Great game with puzzles

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.

Really great puzzle game

Enjoyed very much! Was bummed when I completed the master rank and was no more :(. Need more to solve!!! It took me several weeks on and off to accomplish the very last one though. I was stuck on number eight. Anyway fun to figure out for sure!
