How to play
Tap any column to drop the block shown in the Next box, or aim with the left and right arrow keys and drop with space. The block falls to the lowest free cell in that column.
When three or more blocks of the same colour and the same tier end up touching, they merge into a single block one tier higher — the number on the block is its tier. Everything above the merge collapses down, which can trigger another merge on its own. Each extra link in that sequence multiplies your score, so a well-set-up chain is worth several times what the same blocks would score individually.
The run ends when every column is full. There is no timer and no falling speed, so the only pressure is the board itself.
Strategy that actually works
Keep one column deliberately empty as a dump for blocks you cannot place usefully. Most losses come from having no safe home for an awkward colour, not from bad merges — a spare column converts those dead blocks into a delay instead of a wasted slot.
Build your high tiers along the bottom row rather than in the middle. A tier-4 block stranded mid-board splits the grid into two small halves that are each too cramped to work with, while the same block on the floor still leaves a full column above it.
Before dropping, look at what the merge will uncover, not just the merge itself. The blocks that collapse down are what produce chains, and setting up two same-colour pairs stacked above a pending merge is how single drops turn into four-link chains.
