A mindful, relaxing puzzle game with 99 increasingly challenging, handcrafted levels. Simple to play but not so simple to complete! Immerse yourself in the soothing ambient soundtrack and focus on solving the grid. “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." - an App Store customer from the UK. How to play: 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!

Verdict
The clearest difference is rating: Quadrata at 5.0 against Radiant Grid's 4.2. Quadrata also leads on update cadence (every 5 weeks vs every 6 months) and review sentiment (100% vs 85%). Radiant Grid's advantage is ratings volume (15 vs 1) and price ($1.99 vs $3.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
