Skill Stack

Zip grows skills from small ideas. Place the piece in hand: three alike that touch merge into the next tier, from a Spark up to the Golden Zip. A logic break that trains synthesis: small pieces make big ones, if you leave them room.

Place the piece in hand. Three alike that touch merge into the next tier: Spark, Note, Lesson… up to the Golden Zip.

6x6 · trap the Brainrot · L = Later · U = undo (3)

How to play

Place. Tap an empty cell to place the piece in hand. A ghost shows where it lands.
Merge. 3 alike that touch become 1 of the next tier, on the cell you played. Cascades score x2, x3…
Brainrot. It wanders one cell a turn. Box it in: it turns into a Fossil, and 3 Fossils make an Archive.
The gang. Thumby is a joker, Skip erases a cell, Later keeps one piece aside (key L). Full grid = run over.
Undo. Changed your mind? Take back your last 3 moves (key U). The pieces stay the same: no reroll.

The ladder

Spark · Note: 5 · 20

Scoring

Quick tips

Build in a corner. Keep your high tiers together in one corner so each new merge lands next to the next one up.
Leave room. Every merge needs a free cell. Plan where the merged piece will land before you place.
