Forbidden Island

Forbidden Island is a treasure hunt-themed slot game developed by Naga Games. The game is set against a backdrop of mysterious islands, inspired by exotic locations such as the Amazon rainforest. The visual design incorporates elements of adventure and exploration, with a map, treasure chest, and jungle setting featured prominently.

Core Game and Mechanics:

Forbidden Island features a 5×5 grid layout, departing from the traditional payline structure. Instead, it utilizes a cluster pays mechanism, where wins are achieved by landing five or more identical symbols in adjacent positions, either horizontally or vertically.

The game employs a cascading reels feature. After each win, the winning symbols explode and disappear, allowing symbols above to fall into the empty spaces. This cascade mechanic can potentially lead to multiple wins from a single spin.

A key component of the game is the Mystery Symbol, which can appear anywhere on the reels. When it lands, it transforms into a randomly selected paying symbol, potentially creating or enhancing winning combinations.

The base game is played with a 20x base bet, and players can adjust their wager using bet amount selectors. An Auto Spin feature is available for those who prefer automated play.

Bonus Features:

1. Collection Bar: The Collection Bar is a central feature of Forbidden Island. Winning symbols that explode during gameplay are accumulated in this bar. As players collect symbols, they unlock various island features:
   • First Island: Triggered at 12 or more collected symbols
   • Second Island: Triggered at 30 or more collected symbols
   • Third Island: Triggered at 75 or more collected symbols
   • Forbidden Island: Triggered at 100 or more collected symbols
   The Collection Bar resets to zero when there are no more winning combinations and all possible features have been triggered.
2. First Island Feature: When activated, all low-paying symbols transform into a single low-pay symbol, increasing the potential for wins.
3. Second Island Feature: This feature adds four Wild symbols to the reels in persistent positions, enhancing the chances of forming winning combinations.
4. Third Island Feature: A randomly chosen symbol (excluding the Wild) is added to the reels in a checkered pattern, potentially creating more winning opportunities.
5. Forbidden Island Feature: In this ultimate feature, all low-paying symbols transform into high-paying symbols, significantly boosting win potential.
6. Ante Bet Feature: Players can activate this feature by paying 1.5 times the base bet. When active, it reduces the number of symbols required to trigger each island feature:
   • First Island: 12 symbols (unchanged)
   • Second Island: 25 symbols (reduced from 30)
   • Third Island: 50 symbols (reduced from 75)
   • Forbidden Island: 70 symbols (reduced from 100)
7. Buy Bonus Feature: This feature offers two options for instant access to bonus rounds:
   • Pack 1 (60x total bet): Awards 5 free spins and the First Island feature with all low-paying symbols transformed into one single low-pay symbol.
   • Pack 2 (100x total bet): Awards 5 free spins and the First Island feature with all low-paying symbols transformed into one single high-pay symbol.
   During the Buy Feature, the symbol collection requirements for triggering subsequent island features are significantly reduced.

Unique Aspect:

An interesting feature of Forbidden Island is its progressive bonus system tied to the Collection Bar. This creates a sense of progression and anticipation throughout the gameplay, as players work towards unlocking increasingly valuable island features. The culmination in the Forbidden Island feature, where all low-paying symbols transform into high-paying ones, offers a potentially lucrative climax to the gaming session.
