Clean all the Snow Timer Guide: How the Run Timer Works
Learn when the Clean all the Snow timer starts, why menus don't pause it, and how to react to a yellow or red timer so you can finish a run.
Quick answer
Clean all the Snow is built around a run timer: the official how-to-play line says to clean all the snow before the timer runs out, and the timer starts when the run begins rather than running permanently in the lobby. The in-game HUD shows a percentage and a timer, so treat the clock as a visible constraint alongside your completion percentage. The most important habit is to stop expanding when the timer turns yellow and switch to inspection and finishing when it turns red.
Menus Do Not Pause the Timer
Opening menus does not stop the run timer. A controls guide states: "Opening the Roblox emote wheel does not stop the blizzard timer. Neither does the ChainLemonade shop. Buy, close, move." The co-op guidance adds that if a code drops mid-run, only one designated player should redeem it while everyone else keeps working, because "Six people in a menu is how yellow timers become red timers."
Yellow and Red Timer Discipline
Tips
Yellow timer
Stop unlocking new wings. On the School Map, the same stop-expanding rule applies: if the bar is yellow, do not open another hallway. Beat the timer is the stop-expanding rule.
Red timer
Inspection only. If you are at 80% on red, you already lost Secret; go for a clean Normal or reset.
Why it matters
Yellow is the point to stop expanding and red is the point to inspect and finish rather than open new areas.
Timer Pressure Interacts With Tool Choice, Dumping, and Route Order
Timer pressure changes tool and route decisions. The tools tier list ranks tools "for clearing the house lot and the School Map before the timer expires." The School Map guide warns, "If you bring only a shovel, the timer will eat you in the courtyard," and notes that School dump points sit farther apart than suburban bins, so Max Capacity matters more there: "Fill, dump, return. Do not carry a full canister up the stairs 'for later.' Later is the timer." The tier list also notes that a Vacuum with a tiny tank dumps constantly and can look weak, so dump frequency should be checked before buying another tool. The leftover-snow guide adds that Snow Blowers and Plows should be holstered at the last few percent because they can move counted snow onto clean areas.
Source-Reported Run Length and Map-Specific Timer Pressure
A creator video reports a run length during play: "Apparently, we have 90 minutes to complete this." That is a single creator observation and is not repeated as a verified in-game value by the other retained sources. Map-specific timer pressure is described qualitatively rather than numerically: the School Map guide says the timer "will eat you in the courtyard" if you bring only a shovel, and warns against "standing in the shop reading Molotov while the courtyard timer bleeds." The house lot and School Map are otherwise treated as sharing the same blizzard loop, with dump locations and route order changing between them.
