Fill the screen with falling squares and stack the squares to perfection! Block Flood: Square Rush is a fresh twist on the classic falling-block formula. Instead of clearing lines, your goal is to carefully stack pieces and fill the board to reach a required percentage. The fuller the screen (without overflowing), the better you score
Merge Stack

Slide. Merge. Pop! Merge Stack: Color Block is the satisfying color puzzle that's easy to learn and hard to put down. Swipe to slide the blocks across the board, line up matching colors, and stack five of the same color to make them burst. One clean rule, endless clever moves. Every swipe shifts the whole board, so the fun is in planning ahead. Set up chains, clear crowded columns, and keep your grid open for the next move. Simple to pick up, tricky to master.

Verdict
The clearest difference is in-app purchases: Merge Stack at none against Block Flood's 1. Block Flood's advantage is update cadence (weekly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
