Super Mushroom Man

A projector-first team quiz for ESL classes. A situation appears and the team says what they would say next; the teacher judges the answer. A right answer opens a block, and the block decides the reward.

The game board: 24 lettered blocks and four teams with fruit icons.

How a round works

The points are never safe

A right answer pays one to five coins, or opens a mystery block with one of seven outcomes. A team in last place is never out of it, which is what keeps a whole class watching.

Every scoring rule is a small, pure function with its own tests, and the game's randomness comes from a seeded generator, so any game can be replayed exactly to check what happened.

The game reads its decks from Class Cookies. A subscriber can also play with sentence lists from My Classroom.

The setup screen: sentence deck, level, teams, board size, and mystery block, sound and timer switches.
Setup. Everything is set by default: pick a deck and a level, or just press start.
