Solution
return y==-4 and abs(x)<4 and 9 or abs(x)+z<0 and(x+z)%2>0 and y<1 and(y~=-1 or 7)or x>0 and x<3 and z>>1==1 and y<-1 and 3How it works
Three things on the lane, chained together with and/or.
The lane floor is just the bottom layer (y=-4) painted YELLOW across x=-3 to 3.
The pins form a triangle using a neat condition: abs(x)+z<0. This draws a diagonal boundary where pins only exist in the “back” of the grid. A (x+z)%2>0 checkerboard thins them into the classic pin arrangement. Most layers are WHITE, but y~=-1 or 7 flips the y=-1 stripe to RED for the pin necks.
The bowling ball is a tiny 2x2x2 BLACK cube sitting behind the pins. z>>1==1 is a bit-shift trick that matches z=2 and z=3 in one check.
