Trumpen (2021)

TrumPen is a card game system that uses dry erase cards for players to write the suit and rank on the cards themselves. The game comes with four rulesets for different games to play with these unique cards.

In TrumPen Poker, you mark 5 cards while trying to avoid duplicating cards with the other players. If the same cards are written by multiple players, the player with stronger hands will be eliminated from the game. Among the remaining players, the player with the strongest hands wins.

In TrumPen Blackjack, you collect played cards so that the sum of the numbers you have is as close to 21 as possible. You score points depending on the sum of the numbers you have. The winner is decided after 3 rounds.

In TrumPen Trick Taking, you play 3 tricks per round for 3 rounds, therefore you play 9 tricks in total and score the points. Write down the numbers to 3 cards when they are dealt, then write the suit when you play. This is a trick-taking game with must-follow, no trump, and no bidding.

In TrumPen Speed, you play your cards in a way that cards are stacked in sequential order as quickly as possible. The player who played all of their cards first wins.
