๐One-button games
A single tap, click or key press is all the control you get in these one-button games, so timing is everything. Flappy Jet flaps to keep your jet between the towers, Stack Tower drops a sliding block onto the pile, and Color Dash bounces a ball through spinning rings of colour.
About one-button games
Cave Flyer works a little differently, climbing while you hold and diving when you let go, and Stack 3D brings the stacking idea into 3D. Because there is so little to learn, these games are easy to play on a phone held in one hand. The challenge comes from the speed and precision they ask for, not from the controls.
