A colourful tile problem

How to play

Each square tile is split into four coloured triangles — one colour per edge. Place every tile on the grid and rotate them as needed.

Where two tiles touch, their shared edge must be the same colour. Pieces that have coloured sections missing are edges or corners.

Daily puzzles use a fixed grid size. Each daily puzzle has exactly one solution.

Weekly challenges give you a larger set of tiles. Find every valid smaller grid layout that uses the tiles correctly — several solutions may exist in the same week.

Examples

The diagrams below show what valid and invalid tile placement looks like. Coloured segments must meet matching colours where tiles touch; empty segments belong on the outer edge of the layout, not in the middle.

Valid placement

Valid tile placement: touching coloured segments match, and missing segments appear only on the outer edge.
Touching segments share the same colour. Tiles with missing sections sit on the edge or corner of the layout.

Invalid placement

Invalid tile placement: mismatched touching colours, interior gaps, and coloured segments on the outer edge.
Three common mistakes: touching segments that do not match, missing segments in the interior, and coloured segments left exposed on the outer edge.

Weekly Challenge

The weekly challenge consists of 30 tiles, which can be arranged into a 6x5 rectangle in only one valid way.
Subsets of the 30 tiles can also be arranged into smaller rectangles.

The challenge is to find as many ways to arrange the tiles into valid layouts as possible.
The game interface will give you a list of the possible solutions by size.

Important note

The current version of the solution checker can't handle extra tiles in the grid. Make sure to clear any unsued tiles out of the grid when you find a solution.

An example weekly solution

A subset of the given tiles arranged in a valid 5x2 grid.

Hints

You can buy a hint for any of the expected solutions by clicking the hint buttons. Once a hint is bought, you can re-view that hint for free.

The "Tiles" hint will highlight the tiles that are used for that solution.

The "Corners" hint will place the corner tiles into the correct places in the grid.

Note that each hint costs 5 points and you will only score 1 point per tile per solve.
So be careful with the amount of hints you buy (Buying both hints for a 3x3 puzzle will cost more than the 9 points you'll get for solving it)
