This level-based slot/production that Microgaming released/distributed in 2014 (the actual developer is RABCAT Studio), is trying to engage the players more for entertainment than for huge payouts. The slot comes on a 5×3 grid and 15 fixed paylines. It exhibits Low-Medium Volatility, and the theoretical RTP index shows 96.47%.
While the visuals are stunning, and the ideas for the gameplay are super exciting, there are also some drawbacks to be mentioned. The Castle Builder Slot doesn’t offer Free Spins, Multipliers, Jackpots or other special boosters (a huge disappointment from a technical point of view).
Instead, the developers embellished the game with B/L/W – Build/Love/Win features:
- Build – Completing any of the 35 different castles/palaces construction. Discovering 3 medieval kingdoms.
- Love – Matchmaking the most beautiful princesses with 100+ mighty kings, princes, and other worshipers.
- Win – Receiving 30+ rank-up medals and badges, plus 10+ rewarding achievements.
- Try your building skills now for free in the DEMO mode right here on our site. No signup is required.

Gameplay and Bonus Functions
There are 3 stages and 4 types of symbols at this slot: Royal symbols, Treasure symbols, Building symbols, and Wilds (check at the bottom of our article their description).
Stage 1: Build
- By spinning the reels, you will start building your first castle. Then, by collecting building materials – you supply the constructor (Wild symbol- Old builder) to perform the job.
- Every bulk of materials you gather is indicated in the building meter (upper left corner), showing the progress of your construction.
- Evidently, the more building material coming on the pay lines (left to right) on the reels, the quicker you will have the castle ready.
- The materials are of distinct quality (standard, bronze, silver, and gold, depending on 2x, 3x, 4x, or 5x materials per win line are dropped).
- You most certainly need to build with better materials to make your castle worthy, flashy, and desirable to potential candidates. Plus, with hitting more gold materials, your bonus amount will be larger for the next stage of the game.
- However, you should not only be focused on the building, as the royal and treasure symbols dropping on the pay lines are better paid, and while on the left, the whole construction is ongoing, these symbols are what make your balance move in the main spins.
Stage 2: Love
- You helped to build the castle, and now that it is finished, the Princess settles there. The potential admirers, who begin arriving even when the castle was not ready yet, will be competing for the Princess’s heart. You will be the matchmaker choosing the right suitor. Here via the Pick and Click function, you will have to select among 3 options. Unfortunately, you don’t know what amount is hidden behind the picture of each suitor.
Stage 3: Win rank
- With each finished building, you will advance in rank, and each next level will secure better building symbols on the reels; hence every next castle will be more valuable and lavish. There are 3 separate medieval worlds you can discover, with a variety of settings and projects to build.
