Chesspy

Chesspy is a daily logic puzzle built on one rule. Numbered squares are targets. Place rooks, bishops and knights so each number is attacked exactly that many times. A 0 must stay untouched.

There is nothing hidden: you place the pieces yourself, and one piece can fix two numbers and break a third.

How it works

• 20 boards a day, growing from 3x3 to 6x6. Everyone in the world gets the same boards.
• 3 hearts. You lose one when a move turns a new number red. Removing and undoing are always free.
• Finish and see your Top N% for the day. Sundays bring a harder S-Rank mission up to 7x7.
• No chess knowledge needed. A 3-board tutorial shows you everything.

No guessing

Every board has exactly one solution, and a solver checks that it can be reached by pure logic. Boards that would need a guess are thrown out. If you are stuck, there is always a deduction left to find.

Free, no ads, no account. The browser version has the same daily mission, the Sunday S-Rank, endless runs and joining a friend battle with a 6-digit code. The optional one-time Pro is sold in the iPhone app.
