HOW IT WORKS
Rules of the circuit.
Each player starts with four marbles in Home. Bring them onto your base with an Ace or King, race around the 64-space track, and get all four into your protected finish lane. Finish exactly, and watch out for rivals.
THREE PLAYERS
Every player for themselves. First to get all four marbles safely home wins.
FOUR PLAYERS
Opposite seats are teammates: Coral + Gold vs Teal + Violet. Both partners must finish to win. Once you finish, you move your teammate's marbles.
CARD POWERS
AEnter a marble, or move forward 1 / 11
KEnter, or move 13, capturing along the way
QMove 12, or make the next player discard
JSwap a marble with an opponent's unprotected marble
10Move 10, or make the next player discard
7Move 7, or split the movement across two marbles
5Move any track marble 5, even an opponent's
4Move backward 4 — a strategic shortcut
2, 3, 6, 8, 9Move forward by the card's number
House rules: a freshly entered base is protected until it moves; occupied spaces block movement except a King's capture; you cannot land on your own or your teammate's marble. You may discard one card instead of moving. Hands rotate 4, 4, 5. This is an original Jackaroo-inspired adaptation, not an official rules implementation.
