Puzzle · Intermediate · Keyboard and touchPLAYING PREFERENCES
Discrete-action games to explore with keyboard controls or large on-screen buttons, without holding movement keys.
Choose how to make each move. These selected games use individual presses and taps rather than sustained steering, so you can study the board before acting. A keyboard can move a selection and trigger an action; on a phone, use the visible direction and action buttons. Board tapping differs by game and never replaces every action automatically. Open How to play for the exact controls, including numbered shortcuts and checks.
No continuous held controls; every required action is available through keyboard and visible touch controls.
Open any game below for complete instructions, actual controls, limits and first strategies.
