Features

Sound

The game makes sound effects using the AudioContext API whenever you place a block or score points! Make sure sound is enabled in your browser to try it out. A mute button is provided for those who do not enjoy beeps and/or boops.

Competitive leaderboard

After finishing a game with a high score in the top 50, you'll be asked to submit your name to the global leaderboard. The leaderboard is public and is viewable by anyone playing the game!

Local high score

The game keeps a record of your top score, so even if you're not competing on the leaderboard you can still play just to beat your personal best.

Game replay

When selecting a score from the leaderboard or upon completing a game, you can watch the full replay of the entire game.

Works offline

After loading the web page for the first time, the game will always be available in your cache - so even if not connected to the internet you can continue to play.

Head-to-head

If you start the game as the same time as a friend, you will both have the exact same pieces for the duration of your game - so you can play an impromptu head-to-head game, even with no internet or connection to the other player.

Approachable difficulty

The game is designed to be approachable to casual users, starting at a slow speed. Unlike other block placing games, there are no levels. The speed of the game is based on your current score.

Both keyboard and touch support

Whether playing the game on an iPhone with your fingers or playing the game on an ultrawide monitor with a keyboard, the user interface and controls are designed to be as equal as possible on mobile and desktop.

Other features
