UNO Flex Card Game

''UNO Flex'!' card game is based on the UNO Card Game that players know and love, but with a flexible approach.
Flex cards allow players to "change" their card color (red 4 can turn into green 4 in one round), while "Flex Action" cards allow players to "change" the card's action.
The power card indicates to players whether they are allowed to "change" their cards. The green Ö means "yes" - the red X means "no".
Flex Action cards can "change" to a new action. For example, "Skip" can be changed to "Skip All" and "Draw 2 Cards" can be bent 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! scoring option.
The game is played just like the regular game. The cards left in the opponents' hands earn points for the person who won the round. The first to 500 points wins the game.
