A new brain challenge every day
Daily Challenge is a free brain training game that gives you a fresh puzzle every single day. Each challenge is deterministically generated from the date, meaning everyone around the world gets the same puzzle on the same day. Test your estimation skills, visual perception, trivia knowledge, math reasoning, vocabulary, spatial awareness, and reaction speed across seven rotating challenge types.
Every day at midnight, a new challenge unlocks. You get one attempt to score as high as possible (up to 100 points). Your streak tracks consecutive days played — miss a day and it resets. The calendar heatmap shows your activity over the current month. Share your score with friends and see who can maintain the longest streak.
Yes! A new challenge is generated every day at midnight using a deterministic algorithm based on the date. Everyone gets the same challenge on the same day, and refreshing won't change it.
Your streak counts consecutive days you've completed a challenge. If you miss a day, the streak resets to zero. Your longest streak is always saved so you can try to beat your personal best.
The daily challenge rotates between seven types: estimation questions, visual counting puzzles, trivia, math sequences, word unscramble, spatial reasoning patterns, and speed rounds. Each type tests different cognitive skills.
