Fire Ossan

In Fire Ossan, players take on the role of aspiring summoners competing in a magical qualification tournament. Using Mana cards and Summon cards featuring Monster Girls (and occasionally Ossans) players participate in a series of trick-taking contests to demonstrate their mastery of the summoning arts. While winning tricks is important, success depends just as much on accurately predicting your performance before each round begins.

At the start of each round, players evaluate their hands and secretly bid on the number of tricks they expect to win. During play, summoned creatures compete for control of each trick, with different mana elements influencing the outcome and certain elements acting as powerful trump effects. Careful hand management, timing, and reading your opponents are key to achieving your goals.

Throughout the tournament, players earn points by winning tricks, making accurate predictions, and gaining Evaluation (Impression) points. Balancing ambition with accuracy is crucial, as overestimating or underestimating your performance can be just as costly as losing a trick. After the final round, the player with the highest score is declared the tournament's most accomplished summoner.
