Zebra is a daily logic-grid puzzle inspired by the Einstein riddle, but tuned down for an easier puzzle solving experience. Read the clues, deduce which person sits where, and commit each cell against the clock.

☕ Coffee is a 4×4 daily challenge. 🌊 Deep is a 5×5 bonus grid, available every Friday for people that really love hard puzzles. Every commit is final and counts; your score is the number of times you changed your mind. Zero overwrites is Flawless and big score = bad.

One puzzle a day, the same for everyone, resetting at midnight Toronto time. No accounts (unless you want to sync streak across devices), no hints beyond a single check, no live correctness feedback until the whole grid is solved correctly. Just you and the grid.
