Players in The Game try to discard all 98 cards in the deck onto four discard piles in order to win, but they need to do so in the right ways.
Each player starts with 6-8 cards in hand depending on the number of players, and four discard pile prompt cards are on the table: two showing "1" and an up arrow and two showing "100" and a down arrow. On a turn, a player must discard at least two cards from hand onto one or more discard piles, with cards on the 1 piles being placed in ascending order and cards on the 100 piles being placed in descending order. One tricky aspect to play is that you can play a card exactly 10 higher/lower than the top card of a discard pile even when you would normally have to play in a descending/ascending order, e.g., if a 100 discard pile is topped with an 87, you can play any card lower than 87 or you can play the 97.
The Game on Fire is a mini-expansion for The Game: Spiel... so lange du kannst! that consists of six cards (22, 33, 44, 55, 66, 77). When one of these fire cards is played onto a pile, that card must be covered by the end of the next player's turn or else players have lost the game.
