Big Bad Towers Slot Review
Written by: Filip Gromovic Reviewed by: Nashon Khamala

Big Bad Towers slot is a medieval castle-themed title from Playtech Origins, built on 5 reels with a ways-to-win pay system. The “(95)” version carries an RTP of 95.00%, though Playtech offers multiple RTP configurations for this game, with the highest variant appearing in 99%+ RTP databases. The slot centres on a tower-building Free Games feature powered by three character Perks that modify the bonus round before it begins.
Crown Scatters drive the main feature trigger, while coloured flags on reels 2–4 activate Blue, Green, and Red Perks tied to characters above the reels. A Dragon Wild handles substitution duties in both the base game and Free Games. The Buy Bonus option provides instant access to the tower-building round for players who want to skip base-game grinding.
Below is a full breakdown of how the tower mechanics work, what each Perk does, and what to expect from the RTP and feature structure.
How to Play Big Bad Towers
Big Bad Towers runs on a 5-reel grid with a ways-to-win system. Matching symbols on adjacent reels from left to right form winning combinations without fixed paylines. The base game plays at a standard grid size, but the Blue Perk can expand the layout to 6 rows during Free Games, increasing the total ways available.
Here is how a typical session works:
- Set your bet using the +/– controls.
- Press Spin to activate the 5-reel grid.
- Watch for Crown Scatter symbols. Six Crowns trigger the Tower Building Free Games.
- Coloured flags on reels 2, 3, and 4 send pulses to the three characters above the reels, pre-loading Perks for the next Free Games trigger.
- During Free Games, Crowns landing on tower frame positions upgrade them through four levels. Higher-level towers pay larger prizes when the round ends.
- The Dragon Wild substitutes for regular pay symbols in both the base game and Free Games.
- Optionally, use the Buy Bonus to enter Free Games directly.
The tower-building mechanic replaces traditional free-spin multipliers with a level-based reward system. Each position on the grid can hold a frame, and the frame’s level at the end of the round determines its payout value. This structure means that the order and placement of Crown landings during the feature directly affects the total return.
Bonus Features: Tower Building Free Games, Perks & Buy Bonus
Big Bad Towers channels its feature weight into a single layered bonus system. There are no separate free-spin modes or hold-and-win mechanics. Everything runs through the Tower Building Free Games round, supported by a three-character Perk system, Tower Gate reveals, and a Buy Bonus shortcut.
Tower Building Free Games
Free Games trigger when 6 Crown Scatter symbols land on the grid. The round starts with a set of free spins (observed as 6 in demo testing), and a +1 Free Game symbol can appear during the round to extend it.
Before the first spin, any active Perks apply their effects to the grid. Tower frames appear on various reel positions. During each spin, Crown Scatters that land on existing frames upgrade them by one level (Level 1 → 2 → 3 → 4). Crowns that land on empty positions create new Level 1 frames.
When all spins are used, every frame converts into a tower. Each tower pays a prize based on its final level. Level 4 towers sit at the top of the pay scale, while Level 1 towers return the smallest amounts. The total feature payout is the sum of all tower prizes plus any ways-to-win hits that occurred during the spins themselves.
Flag & Perk System
Three characters stand above the reels: a Blue Warrior on the left, a Green King in the centre, and a Red Hooded Hero on the right. During the base game, coloured flag symbols can land on reels 2, 3, and 4. Each flag sends a pulse to the matching character, pre-loading that Perk for the next Free Games trigger.
Each Perk modifies the Free Games round in a distinct way:
| Perk | Character | Effect |
| Blue Perk | Blue Warrior | Expands the grid to 6 rows, increasing available ways to win |
| Green Perk | Green King | Spreads tower frames across random grid positions before Free Games begin |
| Red Perk | Red Hooded Hero | Creates one frame that starts at Level 4 instead of Level 1 |
Multiple Perks can activate in the same Free Games round if their flags landed during the base game before the trigger. For example, a round with both Green and Red Perks active would start with frames spread across the grid and one of those frames already at the maximum level.
Tower Gate
Tower Gate is a special symbol that appears during winning spins. When a Tower Gate lands, it opens to reveal a hidden symbol underneath. That symbol can be a regular pay icon, a Crown Scatter, or another special element. If the revealed symbol is a Crown, it contributes toward the 6-Crown trigger threshold or upgrades a frame during Free Games.
Tower Gates add an extra layer of anticipation to standard base-game wins, since any winning spin could produce an additional Crown that pushes the grid closer to a feature trigger.
Buy Bonus
The Buy Bonus button sits on the game interface and allows direct entry into the Tower Building Free Games round. The cost is a fixed multiple of the current bet [VERIFY exact multiplier]. This option skips the base-game Crown collection entirely and launches the feature with whatever Perks are currently pre-loaded from flag activity.
Players with fixed session budgets who prefer concentrated feature action over extended base-game play will find the Buy Bonus useful. The internal mechanics of the Free Games round remain the same whether triggered naturally or purchased.
Symbols & Payouts
The symbol set blends medieval siege imagery with standard card royals. Low-paying symbols include J, Q, K, and A. Higher-value regular symbols are themed around the castle setting: cannons, catapults, and the king character. The Dragon Wild substitutes for all regular pay symbols and can appear on any reel.
Special symbols that drive the feature mechanics include the Crown Scatter (triggers and powers Free Games), coloured flags (Blue, Green, Red — activate character Perks), Tower Gate (reveals hidden symbols during wins), and the +1 Free Game symbol (extends the Free Games round by one spin).
During the Free Games round, regular pay symbols still appear alongside the special symbols. Ways-to-win combinations that land during the feature add to the total payout on top of the tower prizes awarded at the end of the round.
RTP & Volatility of Big Bad Towers
The “(95)” designation in the game title refers to the 95.00% RTP configuration. Playtech offers multiple RTP builds for this slot, which is standard practice across their catalogue. HighRTP.com lists Big Bad Towers among Playtech’s highest-RTP titles, indicating that operator-selectable configurations extend well above 95%. Always check the in-game Paytable or Info screen at your specific casino to confirm which RTP version is active.
| Metric | Value |
| RTP (this variant) | 95.00% |
| RTP range | Multiple configurations available (up to 99%+ on highest builds) [VERIFY] |
| Volatility | Not officially disclosed [VERIFY] |
The 95.00% setting sits slightly below the industry baseline of roughly 96%. Players specifically seeking the highest return should confirm whether their casino offers a higher RTP build of Big Bad Towers. Playtech’s configurable RTP system means the same game can run at very different return rates depending on the operator.

FAQ about Big Bad Towers

Yes. The main bonus feature is Tower Building Free Games, triggered by landing 6 Crown Scatter symbols. During this round, Crowns upgrade tower frames through four levels, and each tower pays based on its final tier when the spins end.
During Free Games, tower frames sit on grid positions. Each Crown Scatter that lands on a frame upgrades it by one level (Level 1 → 2 → 3 → 4). Crowns on empty positions create new Level 1 frames. When all spins end, frames convert into towers and pay prizes based on their level.
Three coloured flags activate character Perks: Blue (expands the grid to 6 rows), Green (spreads frames across random positions before Free Games), and Red (starts one frame at Level 4). Perks are pre-loaded via flag symbols during the base game.
Big Bad Towers uses 5 reels with a ways-to-win system. The base grid operates at a standard row count, but the Blue Perk can expand it to 6 rows during Free Games, increasing the total ways available.
Yes. You can purchase direct entry into the Tower Building Free Games round. This skips the base game and launches the feature immediately with any Perks that are currently pre-loaded from flag activity.
The Dragon Wild is the game's wild symbol. It substitutes for all regular pay symbols to complete winning ways. It can appear on any reel in both the base game and Free Games.
The Tower Gate appears during winning spins and opens to reveal a hidden symbol underneath. The revealed symbol can be a regular pay icon or a Crown Scatter, potentially contributing to the Free Games trigger.

Conclusion: Who Suits Big Bad Towers
Big Bad Towers fits players who enjoy layered bonus mechanics with a progression element. The three-Perk system gives each Free Games round a different shape depending on which flags landed during the base game, and the four-level tower upgrade path creates meaningful decisions about where Crowns need to land. The Dragon Wild and Tower Gate keep the base game active between feature triggers.
Players who prefer straightforward free-spin rounds with flat multipliers may find the tower-building system more complex than necessary. The 95.00% RTP on this variant also sits below the 96% industry average, so checking whether your casino offers a higher RTP configuration is important before committing to real-money play.
Start with the free demo to observe how flags and Crowns interact, how often the 6-Crown trigger fires, and how the Buy Bonus compares to natural triggers. When moving to real money, confirm the active RTP in the paytable — Playtech's configurable system means Big Bad Towers can run at very different return rates across operators.
