Description

??????? (Uchronicle) is a trick-taking game from Japan, where players adjust the rules as the go along, but not to break the space-time continuum.

The publisher says:
Uchronicle is one of the trick-taking games in which players repeatedly compare the strength of cards, called tricks. In this game, there are no pre-defined rules for 'strength order of numbers' or specially powerful 'trump cards' that are involved in winning or losing tricks.

Players are obligated to win tricks at all times while changing these rules to be consistent with past win-loss results. Failure to change the rules without inconsistency will result in altering the past - taking unfavourable cards as negative VPs. Try to limit the number of negative VPs you get and win the game!
