They tell you how crowded a week is with games like yours, from calm to crowded:
- Quiet: few games like yours. Plenty of room to be seen.
- Mild: some company, still a comfortable week.
- Busy: a lot of games like yours are fighting for attention.
- Packed: the most crowded weeks you can see.
Each week also gets a heat score. The busiest week you can see sits at 100, and every other week is measured against it, so the scores show how weeks compare with each other.
Green outlines mark your best weeks. A dot marks Steam-wide events like Next Fest and the big seasonal sales, and a star marks a Steam festival your game fits.
Tip: a Quiet week right before a big seasonal sale can still be a tough spot. Look at the event markers too before you settle on a date.
