アクアレギア (Aqua Regia)

Aquaregia is a ladder climbing game about the ionization tendency of metals. Put out the metal cards that will become your hand depending on the field, and get rid of your hand faster than anyone else.

Melt the metal cards in your hand into the field, and the strength of the cards placed on the victory field by the first player who has no cards in his hand is ordered by ionization column, not by number, with lithium being the lowest and gold being the strongest. The field changes in the order of water → steam → acid → aqua regia when everyone passes and the type and number of metals that can be produced differs depending on the field.
