Discrete verbs: Space and arrows
Endless Runner and Flappy Bounce jump or flap with Space or ArrowUp. Tap is equal, not secret. Pattern Pulse and Memory Match are clicks or taps on cells; keys are not a hidden better mode. Reflex Rush is one press when cyan appears—do not hold the key through the wait.
Lane Switch and Gap Drop use left/right or a tap on the lane you want. Arrow Grid steps with arrows. Snake Rush turns at right angles with arrows or WASD; you cannot reverse into yourself. Block Merge and Slide Nine slide the whole puzzle with arrows. Ice Drift commits a swipe or an arrow to a stop.
Continuous verbs: the pointer is the paddle
Brick Breaker, Paddle Duel, and Air Hockey are honest as pointer movement. Keys exist as a backup on some titles (A/D or arrows) but they are not a sniper mode. If keyboard aiming were secretly stronger, we would have failed fairness. Charge games are hold-and-release on a button or on the meter; nudging aim is listed on the playbook when it exists.
Keep Up is tap under the ball. Meteor Tap and Whack Zones are tap-on-target. Slash Dash is a drag through fruit. Color Path is draw-and-undo. Vial Sort is tap source then dest. Peg Jump is tap a glowing landing. If a keyboard shortcut is not in the playbook, it is not a strategy we are hiding.
Pause is part of the instrument
The shared game frame can pause when an ad prompt is up or when you have not started. That is not optional flavor. A jump that happens under a banner is a bug. If a key ever feels like the game did not hear you, say so with the title, the key, and what you expected. Unexplained inputs are defects, the same as unexplained deaths.
The longer control essay in the journal is about fairness of gesture. This page is the map. Use both if you are switching from phone to desktop and wonder why a paddle feels different. It should. The verb changed families.
