Metal Frontiers is a 6-reel video slot that pays anywhere. The game starts with the base game, where a bet of an amount chosen by the player is collected for each spin. From the base game, it is possible to move on to the bonus game or the Risk game.
Each badge has a random multiplier that is applied to wins from symbols of a certain colour.
More than 5 badges of each colour will trigger the corresponding bonus game. Only symbols of the active colour play in the feature.
If more than 5 badge symbols of the same colour appear on the screen, the feature game is triggered for that colour. Bonus games of different colours start with different numbers of bonus spins. Red badges trigger the game with 2 spins, green badges trigger the game with 3 spins. Each winning spin in the bonus game resets the bonus spin counter to its original state. Each feature game contains only symbols of the active colour.
Any new active colour symbol that appears will remain in place on the screen until the end of the feature. The final bonus game wins are calculated after all bonus spins have been completed.
The Risk’n’Buy feature offers players the opportunity to buy a game feature or try to increase their Risk winnings by getting a win multiplier. The maximum multiplier in Risk is x3000 total bet.
Wins are paid for combinations of identical symbols appearing anywhere on the reels. Winning values are based on the currently selected bet and change proportionally as the bet changes. The game is played with fixed bet lines. A malfunction voids all payouts and games.
