The BEND Game is a multiplayer 3D racing game where users can both earn income by competing in the game and earn more with the income stations in it.

With the BEND token, you can buy and modify super cars and participate in races with it. BEND token will be used when selling or renting your super car. In your betting races, you can only set the number of BEND tokens as your bet. Only BEND token will be used as a payment tool when renting billboards and then using them for other advertisements. If you win the big tournament, we will pay you in BUSD or TETHER. The reason for this is to prevent the winner of the race from creating a dump by selling these tokens if we give the prize as BEND tokens. If there is a user who wants it as a BEND token, he can buy the BEND token with the BNB award we will give him.
