I made this P2E game to improve my Solidity knowledge.
    This small game, it works with an interactive ROI system 
    depends on your chance and rarity box, you will get a viking. Then you can join battles.
    # You can only join the battle if you hold a viking NFT.
    # You can join the battle only 1 time per 24h.
    # You will get a $VGD as reward.
    # Reward depends on your Viking rarity (see table below).

    ------ Claim -----

    Well! For a lot of reasons. The claim should be from 10 days to 10 days or plus to avoid price bearish. But it's just a test for players, I'll make it accessible anytime.

    As reward, the contract will give you VGD depends on actually price, but for now it will give 1 VGD for 1 dollar.
    Example : you have an epic viking after fight you can claim 12.5 VGD


    ------- BIG NOTICE -----

    Even if you are a tester not a developer, you still need to interact with python until I create a simple website in the next few days. But I'll try to make it simple, you need just to follow instructions.

  - there's 2 claim methods 
    claim() ==> player can withdraw anytime
    claim5days() ==> player can withdraw 5 to 5 days 
    or you can make it more, replace 5 days with number of seconds/hours/days

  - I tested all functionality on the rinkeby network
  - Opening the box can take up to 200 s you can change it but be careful on time of
