Once Upon a Time is 5 reel, 30 payline video slot game that takes you back, way back to once upon a time when you were a kid and believed in fairy tales. The game is interactive and many of the games featured allow you to join in on the adventure involving dragons and princesses.
What is really great about this game is that it features many symbols that don't actually pay out credits but trigger many different bonuses and features which allow for either instant or easy ways to win additional credits.
Getting three Dragon symbols on position 1 of reel 3 will trigger the Fire Starter Wild Reel. This means that your whole reel 3 becomes a wild reel and is held over the following spin. If you then manage to land the Treasure symbol on the reels while the Wild Reel is active, you get to hold the Wild reel over the next spin too.
Getting the Knight and Princess symbol one next to the other on paylines 1, 2 or 3 you receive an instant credit win. You also have the chance to win free spins by landing three House symbols on any active payline. You also win instant credits and have the option of adding additional free spins during the free spin rounds if you manage the three House symbols again.
There are two second screen bonus games: Goblin's Treasure and Save the Princess, where you are taken into interactive games to win more credits. Besides the bonus game you also have a Click Me Feature which is triggered once you land three Sacks of Gold symbols scattered anywhere on the reels. Click the sacks of gold to find instant credit wins!
