CORNERLOCK.io

Race the island trail, grab today's daily challenge, and claim the board corner by corner — friends, matchmaking, or AI. No ads, just cozy, colorful strategy.

Lock corners. Claim territory. Leave nothing behind.

CORNERLOCK is a fast, friendly strategy game of corners and territory, set in a sunny 3D garden world of grassy islands and candy-glossy blocks. Place your pieces so each one touches another of your color corner-to-corner — never edge-to-edge — and box your opponents out before they box you in. Grab the sparkling gem squares for bonus points. Simple to learn in two minutes, deep enough to argue about for years.

PLAY YOUR WAY • Online — find a match at your level, or invite a friend straight from your friends list. Games start the instant they join. • Vs AI — four difficulty levels, from a gentle warm-up to a genuine expert. • Local — pass-and-play on one device, no account needed.

THE ISLAND TRAIL • An endless adventure map of levels across changing seasons — duels, speed rounds, four-player brawls, and special objectives. • Beat the boss every fifth level to crack open a chest and unlock new block styles. • A fresh daily challenge every day — keep your streak alive and earn extra lives.

BUILT FOR REAL GAMES • Duo (1v1) and Classic (4-player) formats. • Optional blitz clocks when you want the pressure on. • A hint when you're stuck, and a clean tutorial that teaches by playing. • Play a turn now, finish later — online games wait for you, and a "while you were away" recap catches you up on what you missed.

COMPETE AND CLIMB • Skill ratings, a global leaderboard, and weekly seasons. • Hold the #1 spot and your blocks turn to gold — diamond, silver, and bronze trophies for the weekly podium. • Friends list with head-to-head rivalry records — and send a life when a friend runs out. • Your full match history with instant replays — step back through any game. • React with a tap and read your opponent's mood mid-match.

MADE TO FEEL GOOD • A living garden board — flowers, lanterns, drifting clouds — with satisfying bouncy drops, confetti, cheerful music, and cute avatars. • A high-contrast color mode for color-vision accessibility. • No ads. No paywalls. No accounts required to play.
