Perhaps you are right, we could give more, and change the randomizer a bit to get all them back, sooner or later. However, naive it or not, we decided to prove every game and every step. So, before game starts all the foklers sequence is generating for that game and everyone can download password protected zip. As the game is finished, you get the password and may check that you lose not because we wanted it, but simply was unlucky enough to get to that place at that time. Therefore, 1000 Satoshi enough to try the game and decide if you find it interesting or not. If you like it, you can still play for free, using faucet and auction to be able to play. If you don't, you won't need neither 1K Satoshi nor 100K. That's the main idea.
