Casino war is the card game of childhood with a stake on it. Both sides get one card, the higher wins, and a tie offers either surrender for half or a raise to fight it out. A tie is far commoner here than at a card table, since only the rank matters and suits are ignored. Those tie rules carry the whole game: the raise is the only decision in it, and the house keeps its margin almost entirely from what happens when the two cards match.
Bingo replaces the pick with a printed card and the draw with a caller. Numbers come out one at a time and each player marks a card against them until a pattern completes — a line, two lines, or the full card. A ninety ball game and a seventy five ball game differ in the size of the field and in the patterns that count, which is why the rules sheet matters more than it looks.
A scratch card is a draw that already happened. The whole print run is decided before any card is sold, so the prizes are a fixed set distributed through the batch rather than a chance calculated at the moment of play. This is why a card cannot be luckier at one time of day than another, and why the remaining prize table for a run is a more useful thing to look at than the odds printed on the back.
