# WW4 Oracle System **What is an oracle based game?** It's a game which uses a series of mathematical formulae embedded into the game smart contracts so as to maintain and fix the prices of in-game items such as buying WW4 NFT, equipment,... All the prices you see in-game are based on the price of BNB. We also base all game rewards on BNB. You decide when to claim and swap them into $WW4 ## Prices are all fixed in BNB. When you play World War 4, all the game prices and rewards are calculated based on BNB. **For example in your first mission:** * You have earned 0.2 BNB in a mission. Your rewards will show a total of 0.2 BNB * At the time you want to cash out your rewards, let's say market value 1 BNB = 10,000 $WW4 * You will receive 5,000 $WW4 in your wallet ## Why are we using this system? We have participated in NFT games since 2020, our team has studied and realized that most games are unsustainable. At best, they last 3-4 weeks. Our mission and goal are to setup a reliable and fully sustainable game that will last for years to come and still give the player good returns. > **This is why WW4 follows these principles:** > > 1. **To set all in-game prices in BNB and as such, all players will be treated fairly no matter if they are early investors or late investors.** > 2. **To ensure that the players are not losing value no matter at which stage they claim their rewards. All rewards will be exchanged from BNB value to $WW4 value at that time so players have no long-term risk.** > 3. **The closed loop economy system ensures that the game tokens are thoroughly recycled and redistributed in the WW4 project ecosystem.** ## What is the Rewards Oracle? in WW4, we have developed an innovative auto-swap system in order to keep your rewards stable. When you play the game, your rewards will be given as BNB. You can claim your rewards anytime and our in-game system will auto-swap it into WW4 at that exact moment. #### Why is this auto-swap important? Well, many P2E games have a huge problem with keeping rewards value stable. **One day your token rewards might be worth $1000 when the chart is good but few moments later when the chart drops, your tokens might be worth $200.** Here in $WW4, we maintain your rewards value to BNB so that whenever you wish to claim your rewards, you will always be paid in $WW4 based on your BNB value. This is excellent for the durability and economy of the game since players will feel safe playing long-term. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
