Play a field ranger with a pack and binoculars in a textured 3D birch forest with a stream. Twenty-four generated trails each hide a deer, fox, boar or bear. Inspect every muddy print to log its stride, age and heading; the gold arrow and notes tell you which way the animal went and which species it is. Walking is loud and crouching is quiet, and wind carries your scent to the animal, so you must circle downwind. Raise the binoculars from 5 to 12 metres, hold steady for 2.5 seconds and then return to the exit ring undisturbed. Decoy tracks start at trail 5, hard ground with bent grass at 9, a wind shift at 13 and a relocated animal at 18.
Best score, unlocked trails and successful UTC Daily streaks save locally. An active trail position is not saved. Replaying a trail never relocks progression.
The UTC date deterministically chooses a trail and seed. Only a completed identification and exit advances the streak, at most once per date.
Three or more friends can compete on the same seeded first trail. Real banked scores feed the shared scoreboard and final podium. Site computers are score-based opponents, not rangers in the forest. A room permits one run, without local retry or level switching; the room clock continues while paused.
Noise or scent pushed its alert bar to full. Crouch, stay downwind and observe from a distance of at least 5 metres.
Hiding or blurring pauses the simulation and requires explicit resume. Enable WebGL and hardware acceleration if the forest cannot load. Lost context displays a reload recovery message without deleting saved progress.
