Doubles
Build the stack. Every tile is known in advance.
A calm number-stacking puzzle. The whole bag is laid out before you drop a single tile — so every level is a planning problem, not a guessing game. Tap a column, watch equal tiles merge, and match the target stack exactly. Six hand-built levels, no timer, no score.

zenHow to play Doubles
Doubles takes its cue from tile-merging games like 2048, but flips the randomness off: the bag of tiles for each level is fixed and fully visible from the start. That turns it into a small logic puzzle instead of a luck-based one.
Read the bag first
Every tile you'll ever drop this level is already lined up in the bag strip, in order. Scan it before your first tap — the whole level is solvable from what you can already see.
Merges chain
Two equal tiles merge into the next size up — and if that merge creates another equal pair, it merges again immediately. One well-placed tile can cascade several sizes up a column.
A finished stack isn't safe
Matching a target early doesn't lock the column. A later tile — even a small stray 2 — can land on top and merge its way through a stack you already finished, undoing it. Keep every column in mind, not just the one that looks done.
Height caps bite before you expect
Each column has a height limit. A tile can still land on a same-value tile at the cap (it merges away), but a bigger tile with nowhere to merge simply won't fit — plan for the ceiling, not just the floor.
Nothing is lost by trying
Running the bag dry or getting stuck just ends the attempt — Undo walks back one tile at a time, and Restart resets the whole level. Solved levels get a small dot on the picker, but there's no score and no timer chasing you.
