NFT Game multiplayer

Job ID: 32852135

Budget: $3,000 – $5,000 USD

I am looking someone who can create a nft game, Where you import currency from specific crypto currency and get people to spend money on buying different item in shop to fight/race each other to earn?

Each item will raise the percentage to win but never more than 60%

The winner will get the entries fees - 10% fees

Thinking about game maybe like bomberman up to 4 players or racing game up to 4 players, arena type where you have someone fighting other when he is online or offline but has the defense up to be top 10 of leaderboard

Need to make sure i can add more items at anytime of my choice, i think browser type will be good and easier so i can have an admin panel to add items, change price

i dont mind open source game that you customized to my design like this one
