Rectangle2.04

Rectangle is a logic puzzle about seeing shapes in a grid of colors.

Somewhere on the board, four tiles of the same color sit on the corners of a rectangle or a square. Find them, tap them, and they are yours. The bigger the shape you spot, the more points it is worth — and every tile inside it is replaced, so the board never stops changing.

Easy to learn in a minute. Harder to play well, because the pattern you are looking for was created by the move you just made. It rewards concentration rather than fast tapping, and gets harder as the colors multiply.

HOW IT PLAYS
Tap four tiles of one color on the corners of a rectangle or a square. The larger the area it covers, the higher the score. The tiles inside are replaced with new colors, so every solved shape rearranges the board.

WHAT YOU CAN SET
• Board size: 9 x 7, 9 x 9 or 9 x 11
• Session length: 2, 4, 6, 8, 10 or 12 minutes
• Colors: 3, 4, 5 or 6 — more colors means a higher score multiplier
• Music and sound effects, each on or off

WHEN YOU ARE STUCK
• A hint reveals one shape that is really on the board
• Reshuffling deals a new arrangement of tiles
Both cost points, so they are worth saving for when you need them.

A round lasts as long as you choose, from a two-minute break to a twelve-minute sitting. There is no account and no sign-up: open it, pick a length, and play.

A quiet brain training puzzle for anyone who likes pattern recognition, color matching and board games that ask you to look rather than hurry.
