Spinson casino is just launched before the end of 2015 and features top quality softwares like NetEnt, Microgaming and Play'n Go. Not a bad start for any casino and their new player offerings are 10 free spins which you can claim on Starburst slot or even better is their 999 free spins if you deposit €300 or more.

10 free spins to register, play on Starburst
999 free spins on NetEnt slots, deposit €300 or more
Furthermore players can collect comp points so the more you wager the more you can redeem and convert into cash.
