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.
