The meaning of the game is simple. Buy seeds, grow tomatoes, make more seeds from tomatoes and sell these seeds. The minimum purchase price for seeds is 0.01 ETC (about 18 cents in bucks). After doubling the number of seeds (about 8 hours), they can also be approximately sold at 2 times more expensive. But the sale price is floating and depends on the number of new players and on the deficit of seeds inside the game, so it's impossible to accurately predict the sale price.
