Challenge yourself.
Daily.
One short challenge a day to work your logic, memory, and attention. About 3 minutes a day. Free, no ads, no subscription.
Memorize the pattern
Hold 8 tiles in mind. They vanish in 5 seconds.
Built for focus
No feeds. No ads.
Just challenges that move the needle.
One challenge a day, the same for everyone
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.
A mix of logic and memory
Sudoku, Maze, Lights Out, Water Sort and many more. Each one works a different skill: visual memory, spatial reasoning, planning or focus.
All 16 puzzles →Play it safe or push your luck
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.
See where you landed
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.
A map of how you think
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.
