I made this slot machine with small wheels:

Then I made another with big wheels:

Can someone help me decide which looks better?

If you're going to let people play patterns (diagonals, three parallel rows, 4 corners and center) they need to be able to clearly see all 3 rows. If you're not, might as well make each picture as big as will fit. More importantly - why do the pictures of fruit and stuff look out of focus?

The big wheel looks better, but it still looks a little strange. Slot machines are cropped so that the focus is on the middle x-axis. That area looks dim and therefore less eye catching and exciting than it could be.
