Earlier today I set you the following six problems, created by The Grabarchuk family, who are from Ukraine, and who are well-known international creators of puzzles. For more about them see the previous post.
I’ve presented the problems together, with the solutions together at the end.
1. Hex vex
Which digit should replace the question mark?
2. Ring ding
Which system of rings differs from the others?
3. Snake shake
Which view of the 11-cube snake is incorrect?
4. Box fox
Put a digit in each box so all 8 equations, across and down, are all correct. One box already has a digit.
5. Sign mine
Which of the signs in the bottom row should replace the question mark?
6. Ele-mental
For each of these six elements, find another element that has no letter in common with its counterpart. Each answer is unique.
Solutions:
1. Hex vex
2. Ring ding
3. Snake shake
4. Box fox
5. Sign mine
6. Ele-mental
