Five levels, no guessing
Coffee Break, Second Cup, Do Not Disturb, Barely Hanging On and Unhinged. Every puzzle has one answer and can be solved by logic alone.
Hints that teach
Ask for a hint and it points the way. Show Why explains the reasoning, step by step, so you learn the move instead of being handed the number.
Head to Head
Race a friend or another player through the same puzzle. First to finish wins, and three mistakes ends it.
The Game of the Day
The same puzzle for everyone in the world, chosen from the date, so nobody picks it, not even us. See where you finish among your friends.
Honest puzzles, always
Every puzzle is picked with the system's secure random generator and is never chosen by your wins, losses, spending or skill. A rank on the thirteen step ladder, from Fresh Pot to Legend, is earned one solve at a time.
