UpWord: Word Stack Game

Make your mark: pick a neon avatar, unlock more as you win and stack, and size up rivals straight from their profile.

UpWord is a turn-based word game with a twist you won't find anywhere else: you can stack tiles on top of tiles.

Play crossword-style across a glowing neon board, then go vertical — build a new letter on top of an existing one, up to three layers high. Every layer multiplies that tile's value (×2 on the second, ×3 on the third), so one clever stack can swing the whole game. Only the top letter counts towards words, and a three-high square locks for the rest of the match.

FEATURES • Stack to score — the tile-stacking twist turns familiar word play into fresh strategy • Practise anytime — play offline against three bot difficulties, from warm-up to ruthless • Challenge friends online — turn-based matches you pick up whenever; share a code to invite anyone • Learn in a minute — a quick How to Play walks you through the rules and scoring • Clean neon interface, built-in dictionary, live scoring, swap and pass

HOW STACKING WORKS

1. Someone plays a word — say CAT.
2. You stack an R on the T to make CAR — that R scores double.
3. An opponent stacks again to make FAD — the new tile scores triple, then locks. Transform your own words, ladder your own stacks, set up multipliers — building on your own tiles is fair play.

Free to play, with an optional one-time Remove Ads purchase.
