Spell Stack

Spell Stack is a fast, clever word game where the letters never stop falling. Swipe across touching tiles — up, down, sideways, even diagonally — to spell words and clear them before the stack reaches the top. Every word you clear sends the tower tumbling into new words.

FIND THE GLOWING LETTERS
Rare neon tiles carry score multipliers: ×2, ×3, ×4 and the golden ×5. Route your word through one and the whole word pays out multiplied. Only one per word — choose it well.

TWO WAYS TO PLAY

Survival — the endless classic. The pace rises as you improve; big 7-letter words blast the bottom row, hot streaks freeze time, and a shuffle can save a locked board.
Blitz — two minutes, one score. Faster falls, a fuller board, and a countdown that doesn't care how clever you are.

THE DAILY CHALLENGE
One board a day, the same for everyone, one official attempt. Practice after, share it with friends, and build your streak — the 30-day badge is waiting.

CHALLENGE YOUR FRIENDS
Send a challenge by message and your friend plays the exact same board — same letters, same multipliers, perfectly fair. Go one-on-one or in groups up to 8, hide your score until they've played, make it best-of-3, then hit rematch. No account needed — just your name.

MADE TO FEEL GOOD
Two looks (classic Letterpress and sunny Candy), an original soundtrack for every mode, and a dictionary of over 144,000 words with Australian, British and American spellings — COLOUR and COLOR both score.

EARN YOUR BADGES
Sixteen milestones, from your first word to Iron Streak. Your longest words, best multiplier plays and word-length stats are all tracked.

Free to play. Ads can be removed forever with a single one-time purchase — and the optional watch-an-ad Second Chance always stays your choice.
