UpWord: Word Stack Game

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. Words, but with altitude. Download UpWord and start stacking.
