Start your daily
challenge habit.
Welcome to Challenge Me: one short challenge for your mind, every day. Here's how it works.
- 01
Sign in with Apple or Google
One tap with Apple or Google. No forms, no passwords. Your progress syncs across your devices from day one. Not ready yet? Try a few puzzles as a guest; nothing is saved.
- 02
One challenge a day. The same for everyone.
A new challenge goes live every day at midnight UTC: a short run of logic and memory puzzles that takes about three minutes. Every player gets the same one, you get one attempt, and no two days play the same.
- 03
Beat the clock. Mind your hearts.
The clock keeps running and wrong answers cost hearts. Run out of either and the challenge ends. Along the way you choose: skip a round you are unsure of, cash out and keep your points, or keep going for more.
- 04
See exactly how you did.
Each challenge ends with a 0–100% score, your rank among today's players and a comparison with the all-time average. Once the day is over, walk through every round with its solution.
- 05
Get to know how you think.
After a few challenges your Brain Map fills in across eight skills. The Coach shows your strengths, your blind spot and what to train next. Practice lets you train any skill at the difficulty you choose, without touching your daily result.
- 06
Climb the monthly leaderboard.
Your points add up on a monthly leaderboard with players worldwide. You decide how you appear: under your name, anonymously or not at all. On the 1st, everyone starts from zero.
That's it. One challenge. Every day. Build the habit.
