One short challenge a day to work your logic, memory, and attention. About 3 minutes a day. Free, no ads, no subscription.
Hold 8 tiles in mind. They vanish in 5 seconds.
Built for focus
A new challenge goes live every day at midnight UTC, and every player gets the same one. About three minutes, one attempt, and no two days play the same.
Sudoku, Maze, Lights Out, Water Sort and many more. Each one works a different skill: visual memory, spatial reasoning, planning or focus.
A ticking clock and a few hearts keep you sharp. Along the way you choose: skip a round you are unsure of, cash out and keep your points, or play a wild card for a bigger reward and a bigger risk.
Finish with a 0–100% score and your rank among today's players. Once the day is over, walk through every round with its solution.
The Brain Map tracks eight skills, from memory and logic to planning and intuition. The Coach shows your strengths, your blind spot and what to train next, and Journey shows how you have changed since your first game.
Pick a skill or a single puzzle and the difficulty you want. Practice never counts toward your daily result or the leaderboard, so you can warm up or learn a puzzle with nothing at stake.
Your daily points add up on a monthly leaderboard with players worldwide. Show your name, play anonymously or stay hidden: you choose what others see. On the 1st, everyone starts from zero.
Each month brings its own look and its own themed puzzles, so the app changes with the seasons.
No ads, no subscription, no trial and no paywall. No third-party trackers or ad networks, and we never sell your data.
Simple by design
One tap with Apple or Google. No forms, no passwords. Your progress syncs across your devices, or try a few puzzles as a guest first.
A short run of puzzles, the same for every player. Beat the clock, mind your hearts and decide as you go: skip, cash out, or keep going for more.
Finish with a 0–100% score and your rank among today's players. Your points add up on the monthly leaderboard, which starts fresh on the 1st.
