Space Miners is a great new retrowave themed blockchain game which lets you "mine" an ERC20 token known in the game as "Kerium Crystals". This game blends just the right amount of gambling and trading dynamics. Kerium Crystals can be sold back to the game at anytime for a dynamic price, set by a bonded curve algorithm. This is similar to how the Bancor Protocol operates. A bonded curve works by dynamically changing the price of the token in sync with the changing supply reserve. ie As more Kerium Crystals are mined, the higher the price of each become. This behavior encourages miners to hold on to their tokens, and to trade at a later stage. More of this process is explained in the video below:

To mine the crystals in the first place, players purchase and send mining craft to the surface of the planet. Each miner costs 0.02ETH per craft. Once 6 miners have been sent to the planet, the round ends. 3 our of the 6 miners will return back to their players with Kerium Crystals. This is the gambling element. Now the miners have the choice when to burn their crystals. Burning their crystals reward the players with ETH, but also cause the price of the crystals to drop.
