A game lasts five hours in the park (13:00 to 17:00). Every hour everybody secretly plans a walk of at most 5 steps and confirms with Walk!. You continue from where you stood, or enter through a gate: then your first step from the gate is step 3. You may walk diagonally, except between two obstacles or fences; you cannot step onto a fence. Every step on grass wears it one level deeper: trail, path, fixed path. The lowest step number on a free cell makes you its owner; with an equal step number the cell turns grey and belongs to nobody. Then the visitors walk: they never enter the grass first, but follow sidewalk and trails along the cheapest route (sidewalk, path and fixed path cost 2, a trail costs 3). At equal cost they choose the most sidewalk, then the fewest bends, and otherwise they split, the remainder going right. Every footstep of a visitor on your cell is a point. When five or more footsteps land on one cell, that owner's stretch along the routes of those groups is closed for an hour and is grass again afterwards. Cells where nobody walked for an hour grow back one level. In one hour between 14:00 and 17:00 a school trip of 5 children arrives. The most points after 17:00 wins; an equal score is a draw. With friends and online every player has 30 seconds per hour to plan; whoever submits nothing stands still. A player who leaves keeps their trails behind: they keep their colour but score no more points. The server works out the result and nobody sees another player's walk before the hour closes.

Example: a group of 3 walks around the corner over the sidewalk for 10. You lay two cells through the grass: a trail costs the visitors 3 per cell, 8 in total. They take your trail and every footstep on your two cells earns a point: 6 points.
