It is a relatively frequent occurrence due to frustration, animosity against other players, or simply bad luck. The term originated from pinball where physically tilting the machine causes some games to flash the word "TILT" and freeze the flippers. Tilt is also common in other games, especially chess and esports.

If a slot machine malfunctions it cannot complete the random selection process, and therefore reverts to a "tilt" mode. When a malfunction occurs some slot machine manufacturers, for engineering purposes, set the reels to stop briefly in a "jackpot" position.

The Union Jack Patent bet is a 9 selection wager consisting of 56 bets: 8 trebles, 24 doubles and 24 singles.

What is a Union Jack Bet? A bet on nine selections, consisting of between 8 and 80 bets depending on the type. Named after the Union Jack due to the way groupings are determined, by laying out the selections in a 3 by 3 grid then drawing lines vertically, horizontally and diagonally to find 8 groups of 3.
