Block Jam

Block Jam is a block-clearing puzzle game where the score comes from how many rows you finish at once. It runs in the browser — no download, no account, no install.

The rules are conventional — fit the shapes, clear the lines — and the tension comes from deciding whether to cash a small clear now or hold the board open for a bigger one. It is a thinking game disguised as a colour-matching one.

On cool games spot this page is the index entry: cover, description, and search terms. The game itself is loaded from a third-party web build in an iframe on Play, so nothing is bundled into the site. It is filed under puzzle, so it appears alongside the rest of the puzzle games in the catalog.
