Syllable Stack

A falling-block puzzle where the lines only clear when your letters spell a real word.

How to play

Chunks of letters fall one at a time into a narrow well. Slide and stack them so that a complete row, read left to right, spells a valid dictionary word — the moment it does, that row clears and the stack above collapses down.

• Each piece is a syllable-sized chunk: a single letter, a pair, or an affix like UN-, RE-, -ING, -LY or -ED.
• Fill a row that reads as a word (e.g. UN + FI + T = UNFIT) to clear it and score.
• Affix chunks score a bonus, so plan around prefixes and suffixes.
• The fall speed rises with each level — clear words before the well stacks to the top.

Controls

• Desktop: Left/Right arrows move the chunk, Down soft-drops, Space hard-drops.
• Phone & tablet: on-screen buttons for left, right, soft drop and a wide Drop button.

Game modes

• Daily: everyone gets the same seeded stream of chunks to compare scores.
• Practice: an endless random run to sharpen your word-building.

Tips & strategy

• Leave a gap for short connector letters so half-built rows can still resolve into a word.
• Hold an affix chunk over a near-complete row to snap a long word together for the bonus.
• Keep the stack low and flat; a tall jagged well kills your options fast.
