Overview
Empty your hand the fastest, by playing cards higher than odds, lower than evens, and cards which are the reverse of what the active number is
Turn
On a turn, you must try to play a card on top of what came before
If the current card is odd (+), then you must play a higher card
If the current card is even (-), then you must play a lower card
If you cannot meet this requirement, then you have to draw a card
If you play a card in the 11s, 11, 22, 33, 44 and so on, you get another go straight away
If your last played card is the next card you see, i.e. no one else could play, you can play any card ignoring odd or even rules
You can interrupt out of turn by playing a mirror of what is displayed, this is the numbers in reverse e.g. 57 can be interrupted with 75, units and whole tens are mirrors of each other e.g. 02 vs 20
If you successfully play a mirror, either discard a card of your choice (not to the play area, out of the game) or cause everyone else to draw a card
If you play an invalid card, either normally or the wrong mirror, you take it back and draw a card as penalty
Round End
The round ends when a player empties their hand
Every other player scores 1 point for cards remaining in hand, and 2 points for a card of the 11s in hand
Then the cards are shuffled and a new round starts
Game Ends
Once a player meets or exceeds 25 points, the player with the lowest score wins!
