You quoted the maximum for Satoshi Dice and where is the maximum for Satohi Slots stated?
Also, I recommend to make screenshots of everything, terms and conditions, winner, etc.
SatoshiDice and SatoshiSlot are both accessible from satoshidice.com, SatoshiSlot does not have its own website.
The quote I gave is from the "Bet on the house" page where one can invest in the bankroll which is shared between SatoshiDice and SatoshiSlot.
I have made screenshots and can post them if requested. But anyone can see the terms without logging in by going to
https://www.satoshidice.com/ and clicking "Bet on the house".
