Look. Remember. Tap. A pattern appears on the board. The tiles flip face down. Can you find every one you saw? Memree is a memory game built on one simple idea, and it gets hard fast. Start on a 4×4 board with a few seconds to look. Work your way up to Extreme: a 7×7 board, as little as one second to look, and only two lives. THREE GAMES IN ONE • Squares: Memorize the highlighted tiles, then find them all. • Colors: Take in a board full of color, then tap every tile of the color you're asked for. • Glyphs: Remember where each emoji was hiding. The ghost, the rocket, the pizza. Which tiles were they under? QUICK TO START, HARD TO PUT DOWN • A new Daily Challenge every day, the same board for everyone. Keep your streak going • Four difficulty levels, from a gentle warm-up to a blink-and-it's-gone challenge • No clock while you recall.

Cognitive Challenge is a brain-training game built on the Stroop effect — the classic psychology test where the word and the ink colour disagree, and your brain has to fight the urge to read. In practice: the word BLUE printed in red. Tap the ink colour, not the word. It sounds easy. It isn't. That tiny pause is your brain overriding a habit — and training it is the whole game. FOUR WAYS TO PLAY • Classic — tap the ink colour • Reverse — ignore the ink and tap the word • Speed — the same challenge with less time • Tricky — word and colour randomly match or clash, so you never settle into a rhythm BUILT TO TRAIN • 8 colours and endless generated rounds, so there is nothing to memorise • Levels that unlock as your score climbs • Instant feedback with haptics, so mistakes actually land • Statistics that show how you really perform, not just your best score • Daily streaks to keep the habit going WHY IT WORKS The Stroop test has been used to measure attention and cognitive flexibility for nearly a century. Cognitive Challenge turns it into something you can practise in two minutes a day. Works offline. No account, no signup. Free to play, supported by ads.
