Stackbrook: Block Puzzles

Stack falling blocks, merge numbers, slide tiles, then rest with calm sounds.

Stackbrook brings three classic puzzles and a quiet corner into one small, offline app. Drop falling blocks into place and clear full lines. Merge equal number tiles until you reach 2048. Slide fifteen tiles back into order. When you need a break, open Calm and let soft rain or a slow shore play while you rest.

How to play Blocks

1. Move each falling piece left or right and rotate it with the on-screen buttons. You can also tap the board to rotate it or swipe across the board to move it.
2. Use Down for a soft drop, or Drop to place the piece at once. A full row clears and everything above it falls down.
3. Every ten lines raise the level, and the pieces fall faster. The game ends when a new piece has no room to appear.

How to play Merge

1. Swipe in any direction to move all tiles at once.
2. Two equal tiles that meet merge into one, and their value goes into your score.
3. Reach the 2048 tile, then keep going for a higher score.

How to play Slide

1. Tap Shuffle to mix the 4×4 board. Every shuffle can be solved.
2. Tap a tile in the same row or column as the gap to slide it.
3. Put the tiles back in order from 1 to 15 in as few moves and seconds as you can. Stuck? Tap Solve and watch the board put itself back together.

Progress

Each game keeps its own records. In Blocks, every ten cleared lines raise the level and speed up the fall, so each run is a new test of how long you can keep the board clear. In Slide, try to beat your fewest moves and your fastest time.
