Game wise, the logo 'Liquid Gold' is the Wild symbol, 5 of which pays 5000x the line bet. It only substitutes for other symbols, except for the Scatter symbol, it doesn't double any wins, it doesn't come stacked nor become expanded. A dumb Wild symbol. The Bonus Scatter pays 50x the total bet for 5 of them, and getting 3, 4 or 5 of them triggers 10 free spins with all wins doubled. More free spins cannot be retriggered. The other symbols in the game pay from 2000x the line bet to 75x the line bet for 5 of each kind. A slightly low paytable.
The Free Spins game, with only 10 free spins and with a 2x multiplier, is hardly enough to deliver good payouts. 10 spins would usually need a 5x or higher multiplier to be effective, considering that more than half of the spins would be empty ones. In the worse case, you may even get only 1 spin out of the 10 that pays something. In my play sessions on this game, I've had several such instances whereby only 1, 2 or 3 spins paid out something. So you can imagine the sort of low payouts that would give. Most of the time, these wins would be nothing more than 10x the total bet, with only a few that would pay above 15x the total bet amount. Very disappointing indeed. Even though the Free Spins games do come quite regularly, they hardly do anything good to my credits balance. Everything eventually got drained away in the end.
