Grow a Hermit Crab Shell, Listen to Safes, Avoid Suspicion, and Catch the Bomber

In YADOKARICK, players try to find the right size shell for their hermit crab from beach detritus.

The game consists of two suits, and in addition to a suit and rank, each card has a "shell size". During the game, the lowest card played to a trick will be able to adjust the target shell size up or down. The highest card of each color played to a trick will take the cards of that color with the largest size and add to their hermit crab. The bodies have a maximum size and may have a "roof" card added.


At the end of a hand, positive points are earned for total shell sizes less than or equal to the target, and points are lost for shells that exceed the size or for players who added too many cards to their shell. The player with the most points wins.

In the game, you and your fellow players are master locksmiths who have gathered at a national tournament to open four safes by listening to their sounds. You can try to open them in co-operation with other locksmiths or go for a solo victory by relying solely on your own ears.

You and the other players are suspects in a murder case. Heartless as it might sound, who is actually guilty of the crime doesn't matter because in the end all that matters is who is the most suspicious among you!

The criminal search relies on four elements — weapon, motive, place, time — and evidence cards left by the actual criminal is placed face down in the center of the table. Each player also receives a confession card for each of these four elements, and sometimes a confession card will match the evidence card.


On your turn, you can make a statement based on the confession cards you hold or you can investigate an evidence card by revealing a confession card you hold. If you make a statement that matches the evidence, you'll be more suspicious, so you might prefer to investigate — but the fewer statements you make, the more suspicion points you gain at turn's end, so you can't only investigate. Perhaps you can forge evidence to throw off suspicion?

In the end, the player with the most suspicion points loses the game and is arrested.

In Catch the Bomber, a.k.a. キャッチザボマー, you are either the lone bomber in the game or part of the police force trying to catch the bomber. For the bomber to win, they must do one of the following:

• Kill civilians with a bomb.
• Escape the city.
• Restrict the actions of citizens and disrupt the economy.

The police want to stop all of this from happening, but the bomber's identity is secret. On a turn, you either play or move, and the resolution of the game isn't complete until the final card has been played.
