Numbers swirling round and round
Lines of numbers up and down
The few that show beg you to find
their missing mates and fill the line
Cubes in cube and side to side
Which one is missing? Hard to decide
Slowly one appears, then two
Puzzle out the tricky clues
Oh, t's a workout for your brain
if it doesn't drive you insane
Those middle numbers are the worst
They won't come clear -makes me feel cursed!
Finally! the answer's clear!
The boxes filled: Give a cheer!
A HA! You thought you had me there,
But I broke you down by determined stare.
Dust the hands, toss down the pen,
Tomorrow it will start again.
