Ono

Ono is an adaption of the card game Uno for the TRS-80 CoCo.

Cards are graphically displayed on the screen, and the player competes against a single computer opponent. Starting with seven cards, the player and computer take turns placing a card on top of the active card, with the goal to play all cards in the hand. There are four card colors and special cards, and the player can play a card that is the same numerical value or color as the currently active card. If no card in the hand is playable, then the player must take a new card from the pile.
