MindBend
A daily adaptive reasoning puzzle app that gets harder as you improve, inspired by the same puzzles frontier AI still struggles to solve.
Adults and students who want a brain-training habit beyond Sudoku, Wordle, and NYT Games
- One fresh grid-pattern reasoning puzzle each morning with adjustable difficulty tiers
- Streak tracking, performance curves, and a weekly "hard mode" challenge
- "Show your reasoning" walkthroughs that teach logic rather than just revealing answers
- "Beat the AI" mode where you race to solve puzzles faster than popular LLMs can
