Idle Clicker

Controls Goal: make as many cookies as you can in 3 minutes (180 seconds). Controls: press the cookie button (mouse or touch) or Space to bake, and spend your cookies on the buildings below to produce cookies automatically (keys 1-5 are buildings, 6 is click upgrade). Each building costs 15% more every time you buy it, and a click upgrade adds +1 per click (up to 6 levels). The list shows each building's production per second, its cost and its net gain over the time left (what it will make minus its cost); a negative net gain is marked Too late (it will not pay back), and the star marks the building with the best production for its cost. The clock starts on your first click, ends after 3 minutes and stops while the tab is hidden. Score and ranking: the total you have made so far (spending does not lower it), higher is better; the 180-second round has no pause. Tips: early on, click upgrades 1 to 3 pay back much faster than buildings (more so the faster you click). After that, keep buying the starred building, and near the end do not buy anything marked Too late. The tests' best purchase-order search reaches about 26 thousand at 10 clicks per second and about 60 thousand at 20.
