About this game

Every letter is dealt to you. Where it goes is up to you.

Spell Stack: Strategy is a word puzzle about planning ahead, played on a real 3D board. Place each dealt letter, build words across and down, and clear every block before the clock runs out. Each clear adds time, so smart placements keep you going.

HOW TO PLAY
• Place your letter: tap an empty cell to place the letter shown under the board. Undo takes back your last placement.
• Make words: line up 3 or more letters across or down. A finished word glows gold.
• Clear the board: tap the glowing word to clear it and add time. Clear every block before the clock runs out.

LINK WORDS FOR BIGGER SCORES
Words that share a letter clear together: 2 words score ×1.5, 3 words ×2.5, and 4 or more ×4. Every level also has five themed bonus words worth double points, and the clear button shows exactly what you'll earn.

1,000 LEVELS ON A 3D JOURNEY MAP
Travel a living 3D map of 50 themed islands across ten landscapes. Boards grow trickier as you go, with frozen letters, cracked tiles, locked tiles, lift and air tiles, and anchors that hold still while the board shuffles. The dealer favors everyday words, and tough boards get more time.
