300 Shields Extreme bonus features

300 Shields Extreme will look familiar to players who enjoyed the original 300 Shields. An idyllic hillside temple helps create a rural backdrop for the game, though its animation and graphics have sharpened up a little bit since the 2014 prequel.

Low value symbols include the K, Q, J, A, 10 and 9 card suits, with bireme warships, weapons and fighters making up the high value side of the paytable.


Wearing a golden helmet, the Warrior acts as the Wild. It can substitute for any other symbol except the Scatter and it also pays out generously, awarding 40 times the stake for 5 in a winning combination.

300 Shields Extreme Free Spins

The free spins part of this game is called the Battle Feature. It can be activated by landing three or more Scatter symbols, though landing two or more Scatters will award a coin win – 5 Scatters reward with 100x the stake.

Landing 3+ Scatters will trigger the feature with 5 free spins. During these spins, Shield symbols award additional free spins plus a multiplier on any win where a Wild is contributing, up to a maximum of x300.

  • 2+ Shields award 5 additional spins and a x5 multiplier on Wild wins
  • 6+ Shields award 5 additional spins and a x25 multiplier on Wild wins
  • 12+ Shields award 5 additional spins and a x300 multiplier on Wild wins

Buy Pass feature

This feature was not available in the original 300 Shields and serves to add another layer of interest in the Extreme slot’s gameplay. The Buy Pass allows players to buy in to the free spins feature directly i.e. without having to collect Scatters.

It can be activated by clicking/tapping the button on the left of the reel set and it costs 60 times the stake. The Buy Pass also increases the RTP slightly, improving the chances of a win for the player.

300 Shields Extreme has an RTP that ranges between 95.33% and 95.6%, depending on whether the Buy Pass feature has been activated or not. It also has a high volatility, which promises high octane gameplay.
