Place mice from the pile onto the playfield in 
any open spot.

Use the columns to arrange mice in sets of 
"3 the same" or "3 in a row."

Use mouse holes for temporary storage of single 
mice, to help in arranging the "SETS."

Completed sets are removed, freeing up the columns 
to form new SETS. Finish the entire pile, leaving 
only one unplayed mouse to earn bonus points.
