Block Master: Polygonal Puzzle

Block Master: Polygonal Puzzle is a fill-the-board game where the pieces are not squares. You are given a set of polygons, and the task in each stage is to fit them together across the entire playing field. When nothing is left uncovered, the stage is won.

Stages are grouped into categories by difficulty, from the easiest to the hardest, and you are free to start in whichever group suits you instead of working up from the bottom. The developer's stated goal for players is simply to clear as many stages as possible. There is also a leaderboard, so your progress through the levels can be compared with other players' results. The developer pitches the polygon pieces as the point of difference from ordinary square-block games, and that is really the whole idea.

Pick a difficulty group, then choose a stage from it. You are handed a number of polygon shapes. Place them on the board and set them against one another so that, between them, they cover the whole field. Once the board is completely filled, the stage counts as beaten and you can move on to another.

The developer does not list the controls for this game. It runs inside the frame above, so a click or a tap on the game is the place to start.

Since the stage groups run from easiest to hardest and you can start anywhere, the easiest group is a sensible place to learn how the polygon pieces fit together. The aim is full coverage, so before placing a piece, check that the space it leaves can still be filled by what you have left.

An exact-fill puzzle using polygon pieces in place of square blocks. It plays in a landscape frame. Stages are grouped by difficulty, and a leaderboard ranks you against other players as you complete levels.

Cat Block Puzzle has the same goal of covering every cell, using cat-shaped pieces, and Block Triangle Puzzle builds designs out of triangle-based shapes that cannot be rotated.
