UNO Flex Card Game

''UNO Flex'!' card game is based on the UNO Card Game known and loved by players, but with a flexible approach.
Flex cards allow players to "change" their card color (red 4 can become green 4 in one turn), while "Flex... Action" cards allow players to "change" a card's action.
Power cards indicate to players whether they are allowed to "change" their cards. Green Ö means "yes" - red X means "no".
Flex Action cards can "change" to a new action. For example, "Skip" can change to "Skip All" and "Draw 2 cards" can bend to "Each player must draw 1 card".
The player who plays their last card from their hand first wins the game.
If you want to play more than one game, you can choose to use the UNO Flex! point scoring option.
The game is played just like a regular game. The cards left in the opponent's hands score points for the person who won the round. The first to 500 points wins the game.
