LockCross

🔐 LockCross — A Puzzle That Clicks One tap flips more than you think. In LockCross, every safe you click doesn't just open — it flips every other safe in its whole row AND column. One click, a chain of consequences. Chain your moves, plan ahead, and watch a scrambled board fall into place. ⭐ 645 HANDCRAFTED STAGES From a cozy 2×2 warm-up to a brutal 10×10 gauntlet, LockCross packs hundreds of stages that grow in size and difficulty as you go — every single one solvable, every clear earned. ✨ DIAGONAL TWISTS Later stages introduce diagonal special cells, marked with a little purple sparkle. Click one and it doesn't just flip its row and column — it sends the effect rippling down all four diagonals too. Obstacle cells block the chain completely, so every board becomes a real spatial puzzle, not just a grid of switches. ⏱️ RACE THE CLOCK, EARN YOUR STARS Every stage has a fair time limit based on its size, and rewards efficient solving with a 1–3 star rating based on how few clicks you needed. Chase your best time and click count in Records. 💡 HINTS WHEN YOU'RE STUCK Stuck on a tricky layout? Tap Hint to briefly highlight a smart next move — up to 3 hints per set of lives. 🎨 BUILD YOUR OWN STAGES Don't just play — design. The built-in Stage Editor lets you lay out obstacles and diagonal cells, then scramble the board using the exact same click mechanic you play with — so every stage you create is guaranteed solvable. Give it a name and share it with a friend through a single link. No account, no server, no setup. 🚫 NO FORCED ADS. EVER. This is the part we're proud of: LockCross never interrupts your game with a surprise pop-up ad. Ads are 100% optional. Run out of lives? You can choose to watch a short ad for an instant refill — or just wait an hour and get all 3 lives back automatically, completely free. It's always your call, never ours. 👁️ COLORBLIND MODE A built-in palette switch keeps open and closed states easy to tell apart at a glance. Simple to learn, hard to put down. 645 stages are waiting — how far can you get?
