Synonym Stack: Word Match Game

Test your synonym skills!

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Rebuilt from the ground up: thousands of carefully audited words, a handcrafted daily puzzle, the Climb, Blitz and Sudden Death, all wrapped in hand painted night art. The right word is a superpower. Synonym Stack trains it, one beautiful climb at a time. Read a real sentence, feel the meaning, then pick the true synonym from four tempting tiles. Simple to start, honestly hard to master, and every word you learn becomes another brick in your tower. FIVE WAYS TO PLAY • Today's Stack: one handcrafted daily puzzle. Five rungs, one chance, come back tomorrow • The Climb: a stage by stage journey through hand painted worlds, from the forest floor to the summit • Classic: no timer, no pressure, just you and the longest run you can build • Blitz: 60 seconds on the clock, stack as many words as you can • Sudden Death: one life, no net, how far can you go A WORD BANK BUILT WITH CARE Thousands of words and growing, every one reviewed by a human eye: real example sentences that show the word in the wild, choices that are fair but never easy, and a difficulty ladder that rises gently from everyday words to summit vocabulary. This is a game that respects words, and respects you enough to teach them properly. YOUR PROGRESS, EVERYWHERE • A word journal that remembers every word you have truly mastered • Daily streaks, XP levels and a library of unlockable word packs • Game Center leaderboards for your best Classic run and longest daily streak • iCloud sync carries your journal, level and streak across iPhone and iPad SYNONYM STACK PLUS Go Plus and the whole mountain opens: no ads anywhere, free revives in every mode, the full daily archive to replay any puzzle you missed, and every Plus word pack unlocked.
