Alphaza: Stack & Spell

Alphaza is a falling-letter word puzzle — block-drop action meets wordplay. Letters drop one by one; slide them into place and build valid English words across or down. Two letters or more count, and matched words glow and clear.

Chains are where it gets exciting: when letters fall into new words they link for bigger and bigger multipliers, and words that score in two directions at once earn the most. Stuck with an awkward letter? Hold it for later.

• One-thumb controls — drag to move, swipe down to hard-drop
• Hold a letter for the perfect moment
• Chain combos & cross-direction words for huge scores
• Three cozy themes: Twilight, Aurora, Dusk
• Offline, free, no account needed

Quick to learn, hard to put down. How long can you last before the board fills up?
