Kaiawase (Japanese Shell-Matching Game)

Separate each matching pair of painted shells and spread all the halves face down on the floor or table.

On your turn, flip over one shell to reveal its painted pattern, then flip a second shell hoping it matches.

If the two revealed shells form a true matching pair, keep them and take another turn.

If they do not match, turn both shells back face down and let the next player try.

Try to remember where non-matching shells were shown so you can find pairs on later turns.

Once every shell has been matched, whoever collected the most pairs wins the game.
