A procedural 3D treetop sporting park with an articulated runner, backpack, laced shoes, flexible plank-and-rope bridges, anchored rest platforms, trees, flags, waterfall and a soft play-net below. Actual alternating shoe contacts are checked against each tilted plank's projected width, while body lean and dash momentum can cause a stumble. There are 48 deterministic crossings: three short forgiving tutorials, offset narrow planks from crossing 4, dash pacing from 9, rocking-plank timing from 17 and tighter contact windows from 25. Anchored rests settle balance and clear momentum. Normal stars, unlocked crossings and best scores save locally. UTC Daily gives everyone the same crossing and awards a streak only for an achieved win. Opening tutorials last about 11–15 seconds; subsequent tested crossings generally take 20–35 seconds. This is cartoon play-park sport, not real-world bridge safety instruction or a full rigid-body rope simulator.
No. Human room participants independently play the same seeded crossing 12 and compare scores in one finite run. The existing shared Kit supplies rooms, its optional computer competitor Pip and the final podium; Pip is a platform scoreboard character, not an athlete simulated on this bridge.
The seed uses the UTC calendar date. Only a completed winning Daily advances the streak, at most once that date, and missed days reset it. Hidden tabs pause until deliberate resume. Missing or lost WebGL shows an actionable reload control; restored contexts return to a paused run.
