Aqua Blocks is a relaxing block puzzle with an underwater look. The pieces have soft, watery graphics and gentle sound effects, which makes it a very calm way to spend some time. Casual players can easily lose an hour or two to it.
Three block shapes are offered to you at a time. Drag and drop each one onto the board wherever it fits. Fill a complete horizontal or vertical line and it clears, giving you more room. Because you see all three shapes before you place them, you can plan where each will go. The game ends when there is no space left for the shapes you are given, so think carefully about every placement.
When you are in trouble, tap the Aqua Power. It removes a horizontal and a vertical line of blocks from the board, which can rescue a crowded game.
