4 Knight Characters racing against each other to be the first to reach the goal and win the pot of gold.

How to Play:

The Race will start after at least 1 player has bought shares of any Knight Racer then for every new items (power-UP) activated, a 24H countdown will reset.
At the end of the countdown, the players on the first Racer will share the Treasure and everybody else will receive their rewards (no one is leaving the game without values).
