One of the first things you notice when you load the Ding Dong Christmas Bells slot machine is the charming theme song.
The 3x5 grid on which the game is played is surrounded by lights, tinsel, and a noticeboard. There are five bells at the top of this noticeboard, one for each reel that lies underneath it. You have a Rudolf-shaped bell, Santa, a gingerbread man, a tree, and a snowman. In the base game, each one has a unique function to perform.
The reels' symbols are a combination of coloured bells and letters and numerals in the shape of candy canes.
Each time a bell symbol shows up on the reels, it sounds a bell and sends notes to the bell above that corresponds to that colour. The Ding Dong Christmas Bells free spins feature might sporadically activate at this point.
Depending on how many of the bells above the reels were randomly activated at the trigger, the feature begins with 1, 2, 3, 4, or 5 bells turned into Wild symbols. Most notably, these Wild bells have a 2x multiplier value that is applied to all wins in which they participate. In the free games, these bells replace regular symbols in winning combos. The multipliers are combined when multiple Wilds appear in the same combination.
Similar to the regular game, more bells may be activated and turned into Wilds during the Ding Dong Christmas Bells free spins, which can also happen at random. Players get +5 extra spins whenever a new bell rings; but, if multiple bells ring on the same spin, they only get 5 extra spins.
You can purchase the free spins round for 100 times your initial wager. When purchased, the triggering spin may see a random hit of 1, 2, 3, 4, or 5 bell symbols.
