Game Play

Even though Castle Builder II takes the interactive aspect of a slot game to the next level ensure that you play it with a sturdy bankroll-to unlock the various levels doesn’t come cheap.


Bonus Modes

Free Spins

The free spins mode is played when 3, 4 or 5 scatter symbols appear any position across the reels. The amount of free spins you’ll receive are proportionate to the scatters. Three scatters award 10 free spins, 4 awards 15 and 5 scatters awards 20 free spins. Much needed building materials along with other cash prizes can be won during the free spins bonus mode.

Once you’ve finished building a castle a Royal Wedding will be held, the princess will choose the person who built the most castles.

Bronze Cup Challenge

During this challenge your job is to ensure that you get 6 building materials in a pallet. To progress to the silver, gold or platinum levels you’ll need 9, 12 or 15 building materials. A cautionary note, getting hold of the materials needed for the higher levels is difficult. If you succeed the cash prizes awarded will put a smile on the grumpiest high roller’s face.

Free Buildings Mode

After the Bronze Cup Challenge the ”Free Buildings Mode” is the next challenge you’ll square off against. To unlock additional territories you can build any castle you fancy. There are 15 kingdoms of which 9 must be completed first before a Cup Challenge is finished.



Castle Builder II is a great slots that peaks and trows in more ways than we care to remember. It’s a high variance slots with superb yet intricate game play, you must have your thinking cap on when you play it.

To get an idea for the game’s mechanic we advise you to play it in the free version first. From a graphics perspective the game looks really good while its audio whisks you off to far off lands. It’s not your classic slots since there’s far more to it than what meets the eye. It’s a hybrid affair interspersed with its own-styled castle builder theme that plays more like a video game than a slots. It’s also the perfect game for millennials.
