ok i beat it, and i'm surprised by how smoothly the game runs with that amount of math involved
tutorial for anyone who doesn't get it: if you click a square you increase the number of that square, and each square adds its number to the square before it each tick, so if you have 10 on square 3 it will add 10 to square 2 per tick, which then will add to square 1, and the goal is to reach a googol on the first square. You unlock new squares by hitting on the first square the amount it says on the yellow squares, so if the yellow square says 10,000 then you need 10,000 on the first one to unlock it. The circles are the prestige system of the game, they make the game faster overall and you should do it always as soon as possible
TLDR: just click your newest square and prestige as soon as possible
