Puzzles

All puzzles in this round were written by JinHoo Ahn.

This round features Combination puzzles with Instructionless connections. From the IB:

"You’ll receive 12 (8 in the example) puzzles and a set of instructionless rules. Your task is to combine all puzzles into 6 (4 in the example) pairs of puzzles and then solve them.

In every puzzle, there’s a special area marked. This special area has exactly the same shape in every puzzle. When you match two puzzles into a pair, you should apply exactly one of the rules from the provided set of instructionless rules. Each rule describe potential relation between the two special areas. If there’s no rule that can be applied, this means that those two puzzles cannot form a pair. Each rule can be used zero or more times."
