RULES: You may not see the numbers ahead of you. You may not undo. You will spawn in with a number and 9 more multipliers. 0.1x multiplies numbers by 0.1, so use it for the worst and lowest numbers. 0.9x does the same along with everything in between, but multiplies by 0.9. Save it for the highest, most prestigious numbers. Numbers spawn in 100-200. 0% is the worst score possible. 100% is the highest score possible.
Might wanna use the higher slots now or save it for numbers that may not come. So choose wisely. Some rounds are naturally trickier than others. haven't gotten 100 yet:( at least 99% is ok. I rigged it to round down.
