Click the flag and hope it works - if you don't want to watch the grid fill in, TURN ON TURBO MODE (shift+click the flag on desktop). Random/Random matches are on the right, while Set/Random matches are on the left. (scroll for more) Press spacebar if you want, I don't care. :) This just provides checks on randomness - better than clicking a random number generator a few hundred times. The red squares were not matches, while the green squares are. Your probability is the amount of green squares as a percentage - for example, 3 green squares is 3%, and one green square is 1%. (scroll to notes and credits for more) Happy generating!
RANDOM/RANDOM CLOUD VARIABLE IS BROKEN, I think it's a server-side error - but it resets each time the flag is clicked. (Cloud variables will be disabled until this bug is fixed) I was thinking about which probability is closer to 1% - setting a single number then picking a random one that might be the same (Set to Random), or picking a random one and then picking another random one that might be the same (Random to Random). That's why this exists. (Note - In this project, the set number is a 1, and a random number is generated using 1 out of 100). The X change variables are there for myself, as well as the unit number, so disregard those if you want. The cloud variables add up everyone's successful matches, then divides them by the total amount of plays times 100. Using the cloud variables are in an attempt to see how far off a supposed 1% chance is in reality, while you could use different methods as well. All code is originally made by myself (@Happydiggers), as well as the idea - feel free to remix, but give credit!
