Starting with three cups place one upside down and two right side up. The objective is to eventually turn all cups right side up in six moves. You are only able to and have to turn at least two cups over each turn.

WARNING: Spoiler below.
The trick in in the turning rule, "at least two cups..."
Lets mark the cups "R" for right side up and "U" for upside down.
Start: U R R
Flip 1: U U U
Flip 2: U R R
Flip 3: U U U
Flip 4: U R R
Flip 5: U U U
Flip 6: R R R (I flipped all 3 which is allowed)
