Full description
Concentration is a fast, friendly memory game. The cards flash up for a moment — memorize them, then match every pair before the clock runs out. Clear the board, complete each level's missions, and dodge the bombs hidden in the grid. Simple to pick up. Hard to put down. WHAT YOU GET • 50 hand-tuned levels that grow from a gentle starter grid to dense, bomb-laced boards • Endless mode for a never-ending run once you clear the ladder • A new Daily Challenge every day, with its own streak counter • Level missions — find a certain pair on a given turn, or clear the board without hitting a bomb — for bonus points and coins • Power-ups for the tense moments: add time, arm a bomb shield, or reveal a hint • Earn coins as you play, claim a daily bonus, and spend them on power-ups • Star ratings on every level — chase ★★★ across all 50 • Colorful, readable tiles and crisp, tactile animations • Plays fully offline DESIGNED TO FEEL GOOD Concentration is built around one idea: fun first. Every level is beatable with skill alone — coins and power-ups just make a tough board friendlier, never a requirement. No level hides behind a paywall. The interface stays quiet so the grid is the star. FREE TO PLAY Concentration is free. Ads keep it that way, and a single one-time purchase removes them forever. We don't track you across other apps or build a profile — your scores, coins, and streaks live on your device. Ready? Take a breath, watch the cards, and match them all.
