How to play

On a computer, most games in this category use the arrow keys or WASD to move, the mouse to aim or select, and space or enter to confirm and act. On a phone or tablet, tap and swipe directly on the game area. If Merge Defense Pixel Blocks uses its own control scheme, it will show you on the title screen or in its in-game help.

Use the Fullscreen button above the description to expand the game to the whole screen — worth doing on smaller displays, and it removes everything else from view so you can concentrate.

• On mobile, turn the device to landscape for games designed around a wide play area.
