Gridlock (daily block puzzle)

Gridlock, from the small studio Aeterna, came out on Steam in April 2026. The board is a 9x9 grid divided into nine 3x3 squares, and you are given block shapes to drag onto it. Filling a complete row, column or 3x3 square clears it and scores points, and clearing on consecutive placements builds a combo multiplier, with bigger bonuses for clearing several areas at once. The game ends when none of your pieces can fit.

The Daily Challenge is what sets it apart from the many block puzzles of this kind. Each day at midnight every player receives the same sequence of pieces, so luck of the draw is taken out and the result depends on placement. You get one shot at it, and scores go onto a shared global leaderboard.

Free play gives random pieces for practice at any time, with local high scores, and an ad can buy a second chance there. The game is free on Steam for Windows, Mac and Linux, and on Android through Google Play as Gridlock: Daily Block Puzzle, where it carries ads and uses Google Play Games achievements and leaderboards. On Android, free play also works offline, and the app can send a daily reminder when the new puzzle is out.

It suits fans of block-placing puzzles who want a fair daily contest.
