Two teams, each consisting of one man and one woman, competed through two rounds in the main game to win ("steal," in the show's parlance) cash and prizes by uncovering them on a 4-by-4 grid of squares. Various symbols were in the squares:

• Green cash square (6): Win between £0 and £25 by pressing the buzzer to stop a randomiser.
• Swag bag (4): Win a prize, which may be valuable (e.g. a pocket translator) or worthless (e.g. a "12-piece tea set" that was actually a shattered teacup and saucer).
• Burglar mask (1): Steal a prize from the opposing team.
• Jools (3): Play an arcade-style computer game for additional cash. These games often involved Jools' cat sidekick Scruff and/or his arch-enemy, Boxer the guard dog.
• Jail (2): Awarded nothing.

Round 1 edit

A toss-up question was asked, open to all contestants on the buzzer. A correct answer awarded initial control to that team, while a miss awarded it to the opponents. The board was displayed to the teams for 10 seconds, then covered up and rotated 90 degrees clockwise.

The team in control was asked to find a particular symbol (cash, swag, or Jools). If they succeeded, they won whatever was associated with that square. If they found the wrong type or a jail square, they won nothing for that turn. Finding the burglar mask allowed a team to steal one prize from their opponents at any time until the end of the round.

The teams alternated choosing squares, and the round ended when all the cash and swag had been uncovered.

Round 2 edit

Gameplay proceeded as in Round 1, with the following changes:

• There was no initial toss-up question; the team that did not play last in Round 1 had initial control.
• The board was displayed for only 5 seconds and then turned 180 degrees.
• Green cash squares were now worth between £0 and £50.
• Finding a jail square deducted £5 from a team's score.
• Three of the six cash squares now displayed a red background instead of green. If a team found one of these, they had to press their buzzer to stop a randomiser between £0 and £50, and they lost that much cash to their opponents. When teams were asked to find cash on the board, they needed to uncover only the green squares.

The team with the higher cash total at the end of this round won the game and advanced to the bonus round. Both teams kept whatever cash and prizes they had accumulated.

Bonus round edit

Only one member of the winning team played this round. Five special symbols were hidden on the board: a key, bank, alarm, vault, and safe. The contestant had 60 seconds and eight chances to find these symbols in any order. Also hidden on the board were six cash squares (two each of £5, £25, and £50), and five police helmets that each deducted 5 seconds from the clock if found.

The board was shown for 5 seconds before being covered up; the innermost four squares then rotated 180 degrees counterclockwise, while the outer ring of squares rotated clockwise by the same amount.

If all five symbols were found, the team won the jackpot, which started at £1,000 and increased by £500 for each game in which it went unclaimed. The jackpot maximum was £3,000 (£5,000 in Series 3).
