Pullchain

Pullchain is a puzzle about where you put things down.

Each turn you place a single stone. It never moves again — but if it lands beside its equal, it pulls that stone in and doubles, and the doubled stone slides on into the next, and the next. Build a staircase, leave the right cell open, and one drop climbs all the way up.

• No sliding, no swiping: every placement is a decision
• Chains multiply — the longer the run, the more each merge is worth
• When a stone could merge with two, you pick which — or tap the stone itself to pull them all in at once
• The board grows as you do, from 4×4 to 9×9, and brings rocks with it
• WILD stones and BOMBs turn up when you least expect them
• Pick a trait at every milestone and make each run its own
• Keep a stone in the bag for later, and reach for the tools — Breaker, Swapper, Purge — when the board closes in
• Classic mode: an empty board and nothing but numbers
• A half-minute tutorial, then the game gets out of your way
• In 16 languages

No forced ads, ever. A video plays only when you ask for one: a second chance with two bombs when a run ends, or a refill for an empty tool. A one-time purchase removes even those — the second chance and the refills come without the video. No timers. No account needed: your bests go on the global leaderboards under a name the game makes up for you, like Amber Fox 42.
