We can't tell you whether or not Santa is a Peeping Tom, though how he knows exactly if you've been good or not is a real mystery! What is easier to figure out are the spins that can be played in the Santa's Surprise slot. There are 3 coins that can play the base game, however a 4th coin played may add some bigger bonus presents to your potential wins. The coin amount is set at a dollar per coin with a total max of 4 dollars if you add the 4th coin. All payout is based on the 3-coin play with 2500 coins won for the jackpot win.
Landing three of the Santa Stocking on the payline will do the trick! This symbol also helps a bit with substitute wins if one or two land on the line itself. Extra pay worth 2x or 4x is given for each one it subs for. If a present is landed on the 3rd reel while playing the 4th coin this can trigger the bonus round loads of extra wins. Happy Holidays!
