Ensure that the CH334F USB Hub has two USB mice plugged into it, and is connected to the USB Host port on the Metro RP2350 that was wired up previously. Reset the board by cycling power or pressing the Reset button if you happen to plug in a mouse after power up.

Be sure you connect the DVI breakout to an HDMI monitor and the monitor is on. You might need a long cable if your monitor is not near the Metro RP2350 (like a television). The cables are standard and may be obtained from any trusted retail outlet. Also reset the Metro if you plug in HDMI after powering the Metro.

Once connections are all set, power the Metro RP2350 either via USB C (5 volts) or the barrel connection (5.5 to 17 volts DC, center positive).

Gameplay

During the game, players look at the cards on the board, trying to find valid sets of 3. Once a player spots a set, they click the right mouse to buzz in and begin their countdown. They then click the 3 cards that make up the set they found. If the set was valid, they are awarded a point and the cards are removed. If it wasn't a set, or they run out of time, a point is deducted. 

During open play, while no one has called set, the players may click on the "No Set" button in the bottom right corner to indicate they can't find a set and want more cards to be dealt. Once both players click the button, the game will will deal an additional 3 cards, if there is room on the board, or shuffle the cards on the board back in and deal 12 new ones if the board was full.

If both the deck and board are empty, then the game is over and winner is determined by the high score. A more likely game ending occurs if the deck is empty, some cards remain on the board, but both players have clicked "No Set" indicating they cannot find any sets in the cards that do remain.
