Classroom Market

One shared classroom game with four teams.

• Each team has a physical hand of 10 cards.
• Each team starts with £350.
• Each team contributes the chosen bonus-pot amount at the start (default £50).
• The deck has one Common suit, one 8-card suit and two 10-card suits.
• The goal suit is the other suit of the same colour as the Common suit.
• Each goal-suit card pays £10.
• The team or tied teams with the most goal cards split the remaining bonus pot.
• Teams discuss prices, make bid/offer quotes, accept trades, or wait.
• The teacher records trades, can run the timer, or can manually choose when to end the game, then reveals results and reviews hand history.
• Uploaded cards can be TXT/CSV/XLSX. Use one row per team, for example A H:2 D:3 C:3 S:2, or spreadsheet columns Team, H, D, C, S.
• After each trade, all quotes in all suits are automatically canceled and players must enter fresh quotes before anyone can make another trade.
• A trade will be blocked if the buyer does not have enough funds or if the seller does not have any cards of the given suit. This may reveal hidden information.
