Game looks standard for Real Time gaming Slots, same design and same look of pictures, just another sounds, music, pictures, but generally everything is very similar.
Penguin Power slot has 20 pay lines, min bet is 0.20. I am probably never played with this bet size, because with my own money I play 0.40 - 0.60, and with no deposit free chips I bet much higher, game looks good for playing with higher bets, because free spins appear to triggering very often.
During base game there is nothing interesting to happen. Wilds do not have any special extra features or multipliers, and there is no any bonus game or bonus feature. To trigger free spins it is needed to get 3 or more scatters, and interesting that number of free spins does not depends on number of received scatters, like usually in other slots. There is after triggering feature player by random get 5, 10, 15 or 25 free spins. Most times it is 10 or 15, also often 5, and very rare 25.
During free spins feature if scatter and wild appear on one row, than will be triggered penguin power feature, and scatter will award some cash prize or free spins. Most times prizes are very low, but once I got 50x total bet on such trigger, so prizes can be also very delicious. Feature triggered often, and on the end of free spins I usually have nice result.
Overall my experience with this game is OK, like I said I win from two free chips playing this game, it appears that there is very easy to make wagering requirements to clear the bonus and make withdrawal.
