Glymmore is an 18 card game for 2-3 players. Each player has a field comprising cards that have different colours and numbers on each side. Each card's value depends on the colour and number at the top. On your turn you have three actions which you can use to rotate cards and change their value and colour.
Once everyone has had one turn, the top card is revealed, which has an event to change the game. Then, whoever has the most points from their field with a matching colour wins the card. Players have to plan their cards strategically to win more jewels each round.
When there are no more cards left, players group their cards based on their colour. Each player counts up their points. Players gain extra points based on the number of cards in each group and for having the same type of jewels in one group. Who ever has the most points at the end wins!
