How to play

Choose left, right, or both hands and a speed from 1/8×, 1/4×, 1/2×, 1×, or 2×. Camera mode first observes six seconds of gentle movement and places balloons only within that demonstrated comfortable area. You may use touch or mouse instead.

Sit in a stable chair when appropriate, keep the floor clear, and avoid reaching to your maximum. Stop for pain, dizziness, breathlessness, loss of balance, or unusual fatigue.

Possible general benefits and limits

Reaching toward visual targets may provide general upper-limb movement, visual tracking, attention, and hand-eye coordination practice. Camera tracking is not a medical measurement. Scores and estimated movement distance do not demonstrate rehabilitation or treatment benefit. Camera frames are processed in the browser and are not uploaded by this game.
