CHALK HOP — Free Chalkboard Jumping Game with Tilt Controls

A small, original chalk-filled rabbit climbs an endless blackboard of five platform styles. Grab propeller hats, rocket packs and one-hit shields; stomp or shoot the chalk monsters and steer clear of black holes. Desktop uses arrow keys and Space. Tilt your phone or tablet to steer and tap any non-control area to shoot upward, with touch arrows as a sensor fallback. Your highest height stays on this device.

Platforms & play modes

desktop, tablet, mobile. Single-player survival. No human multiplayer.

Controls

The rabbit jumps automatically. Move left/right with Arrow Left/Right or A/D on desktop. Phones and tablets primarily use gentle left/right device tilt from orientation/gyroscope and gravity sensors, with screen rotation compensation, a dead zone and smoothing. Motion permission is requested only from Start or Enable tilt; HTTPS is required. Your first valid reading centers your current grip, and the center button recalibrates it. Denied permission, absent sensors or stale data are clearly reported; on-screen left/right arrows remain available as fallback. No motion data leaves the device. Both orientations work, with portrait preferred on phones; rotating pauses the run and clears input, then resume with fresh calibration. Platforms include steady, moving, crumbling, spring-boosting and fading types. Fading platforms are optional; the generated main route remains reachable. Wrap around left/right edges. The camera follows new height upward; falling below the screen ends the run. Endless ascent has no final stage. Height uses eight game units per meter and the highest run height is saved locally under chalk-hop-best-height; refresh preserves it. Esc/P pauses; M or Sound enables audio explicitly, with every new load muted. No online or local multiplayer and no editor. Controls suppress long-press menus, selection, scrolling, dragging and gesture zoom. All character art and sound are original, not copied from Doodle Jump. Collect a propeller hat for 2.8 seconds of lift, a rocket pack for 1.9 seconds of faster flight, or a shield for one monster collision within 12 seconds. Flight defeats monsters on contact. Stomp monsters from above or fire chalk stars upward using Space or by tapping/clicking any non-control screen area; the 0.24-second cooldown prevents unbounded shots. Sound, pause, calibration, movement, links and information controls never fire shots. Black holes defeat you even with flight or a shield. Enemies and black holes appear gradually in optional side lanes. Every 100 meters shows a brief non-blocking milestone.
