Out of Glass

by Martin Gardner

Solution Step 0/0

A wine glass is arranged from four matchsticks. A cherry is inside it.

By moving 2 matchsticks get the cherry outside the glass. The cherry must not be moved. The glass’s shape must remain exactly the same as the initial one, although it can be in different position and at different rotation.

Two symmetrical solutions exist for this puzzle. What matchstick is never moved in either of them?

Explanations

One of the two symmetrical solutions is shown – moving matschtisks “a” and “c” to the right. The other solution is moving “b” and “c” to the left.

Matchstick “d” is never moved in any of those two solutions.

Check “a”
Check “b”
Check “c”
Check “d”
