Radiant Grid vs SumLock

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!

Have you ever wanted a brain teaser that perfectly combines logic, math, and the pure satisfaction of cracking a safe? SumLock is the answer. Most puzzle games rely entirely on vocabulary or repetitive patterns. SumLock is different. It’s a beautifully dark, immersive numbers game where you use deduction and quick arithmetic to break open a 6-digit master code. Crack the Master Code: You have exactly 4 attempts to break the lock. Each row forces you to think strategically, shifting your digits as you hunt for the hidden combination. The Ultimate Math Challenge: There's a catch! Every single guess must consist of 6 completely unique digits, and their total sum must exactly match the Target Sum displayed at the top of your screen. It's a brilliant double-layer challenge for your mind. Color-Coded Clues: Hit "LOCK IN" to submit your combination and see how the vault reacts. Green means the digit is in the perfect spot; Blue means it's part of the code but needs to move; Red means it's not in the code at all. Build Your Winning Streak: Keep your mind sharp and see how many locks you can open in a row. Save your records automatically and push yourself to beat your personal best streak. Why SumLock? Because giving your brain a quick daily workout should be satisfying, crisp, and fun. Complete with clean haptic feedback, daily reminders, and a distraction-free layout, SumLock is the perfect ritual to test your reasoning skills.
