Plus cards: a player can put a +2 card down if it matches the colour
of the card on the pile. The next player must then pick up 2 cards, unless they have a +2 or +4 (multi-coloured) card, in
which case they can add this to the pile, and the next person then must pick up the total number of cards or place a plus
card down. Nothing can beat a +4, unless you have one you'll usually have to pick up, however, the player of the +4 must state
which colour they wish to change to, if you have a +2 of the colour they chose, then you may place this on top.
Action cards: stop cards, if two identical stop
cards are put down, the next two people miss their turn. Direction change cards, if two identical cards of this type
are put down then the direction continues as normal. A multi-coloured card can be placed down on any colour, the player can
then choose a new colour.
Other rules: If a player have 2 identical cards, they
may put them both down in one play. If a player has an identical card to the
one which is on the top of the deck, they can place the card down even if it isn't their turn, providing they are fast
enough. After a player picks up cards they must be given sufficient time to organise them before game play is resumed.
