59B checkered pattern ! new ultra-golf challenge ! rules proposed on discord

u/New_Core

I didnt read the rules but here is a 48B for(i=166;i--;)x.fillRect(i%24*90,i%14*90,90,90)
u/pavel

Would be good to put the rules here... Can the scale be not 90? Seems like a bad number. 120 fits nicely horizontally and vertically, I'd choose that. Or a power of two for possible bit twiddling.
u/metamero

rules of this one: - full render on first/each frame - full resolution - exact 12 squares on vertical
