Stack & Crush

A single-column twist on block puzzles: swipe to position falling blocks and crush the stack when it tops off.

Core mechanic

Swipe left/right to rotate the next block's orientation as it falls into a 1-wide column; match three to crush.

Controls

Single-thumb swipe horizontally to drop the next block in the right slot.

Theme

Satisfying colored cube explosions identical to Block Blast, but squeezed into one vertical tower.

Why now

Block Blast just hit #3 Casual with 204K ratings; one-thumb single-column is a fresh gap in a saturated genre.

Hook
5/10

Block Blast validates block-puzzle demand at #3-4 Casual with ~4M monthly downloads, but a single-column twist is an unproven niche variant of a known hook.Sensor Tower: Block Blast ~4M monthly downloads, still top Casual grossing

Virality
4/10

Block puzzles have shareable crush moments and live on TikTok, but the subgenre is heavily cloned, making breakout virality difficult for new entrants.Block Blast App Store page confirming genre saturation and near-identical 'More by this developer' clones

Simplicity
8/10

Single-thumb horizontal swipe into a 1-wide column is trivially understood; matched by ready-made hypercasual puzzle kits.Unity Asset Store hypercasual puzzle templates confirm this is a templated, low-build-cost mechanic

Monetization
6/10

Block Blast clears ~4M downloads/month but only ~$10K revenue (~$0.0025 RPD), implying rewarded/interstitial ads work at scale but per-user yield is low for new entrants competing for the same impression pool.Sensor Tower shows Block Blast revenue compressed despite huge downloads

Whitespace
2/10

Market is crowded: Unity templates ship the exact mechanic, Blux Games publicly markets a 'place blocks, clear lines' game with near-identical description, and Hungry Studio ships many Block-Blast-style clones.Blux Games portfolio: 'Place blocks, clear lines, chase high scores — modern take on classic block puzzle mechanic'
