Before kicking off the project, let me introduce the concept behind the game.
As this chapter's name suggests, we are going to build a Tontine game. The concept behind the weird word Tontine appeared at the end of 17th century. Initially, it represented a collective investment scheme plan, where each participant paid a sum into a fund and received dividends from the invested capital. But behind this simple idea, a weird rule is hidden: when a subscriber dies, their share is divided among the others and the last lucky survivor recovers the whole capital.
In our game, we will adapt this idea to our smart contract and gaming logic. Players will deposit funds in the game's smart contract to join the game. Afterwards, they should keep pinging it during a specific time interval to avoid being knocked out by other opponents. For instance, if anybody misses pinging the contract within a day for any reason, the other players are able to eliminate them. So, nobody will die in our case but they will be eliminated. Similar to the original Tontine, the last player standing will win the funds controlled by the contract.
Let's start by preparing the environment in which we'll build the Tontine smart contract.
