Have you ever been unable to stop playing a slot game because you were determined to get a chance to play the bonus round? I have. I played Microgaming’s immensely popular Thunderstruck 2 much longer than I should have, to my wife’s chagrin, because the tantalisingly elusive Wildstorm feature kept being advertised above the reels. Sadly, I still haven’t experienced the awesome Wildstorm feature, but I have made up for it by taking full advantage of Thunderstruck 2’s wonderful free spins rounds. The slots mentioned below made it onto my list of free casino slot games with great bonus rounds because I stuck at it and finally conquered all of these bonus games. Now you have the chance to play these free casino games and slot machines and enjoy their bonus rounds without busting the bank.

Hitman Slot Game

This 5 reel, 15 payline slot machine stays true to the tone of the original video game. The predominantly red and black colour scheme evokes the dangerous, elegantly calculating mindset one associates with Agent 47. The pokie includes wilds, scatters, multipliers, a free spins round, an Insignia bonus and a thrilling second screen bonus game where you need to select and hit a target. When 3 or more bonus icons appear on the reels the bonus game is activated. You are presented with 5 targets. Select one, choose your weapon, perform the hit and claim the reward.

Tomb Raider – Secret of the Sword Slot Game

Tomb Raider Secret Of The Sword Online Pokie

As an avid Indiana Jones fan, Ms Lara Croft greatly appealed to my secret desire to become an archaeologist who jet sets across the globe in search of mysterious relics and ancient artefacts. Any pokie lovers who harbour similar dreams will love Tomb Raider – Secret of the Sword. Follow Lara’s adventures when you play this 5 reel, 30 payline pokie that incorporates wilds, multipliers, free spins, a hidden treasure bonus, a shootout bonus and a very rewarding Global Adventure bonus game.

Great Griffin Slot Game

Great Griffin Online Pokie

Those who enjoy pokies filled with magical creatures, sorceresses, alchemy and enchantment will no doubt have tried Microgaming’s Great Griffin. This 5 reel, 50 payline pokie includes two types of wilds, scatters, free spins, multipliers, and a fun pick me bonus. The wild bonus occurs randomly during the base game and when this occurs the white griffin swoops down upon the reels, turning one symbol into an additional wild. The pick me bonus is activated when three sorceresses appear on the reels, but it’s the free spins round that is really worthwhile. When three or more scatters appear you get to choose which free spins feature you would like to make use of: 5 free spins with a 10x multiplier, 10 spins and a 5x multiplier or 15 free spins with a 3x multiplier.

Battlestar Galactica Slot Game

This 5 reel pokie makes use of the popular 243 ways to win payline strategy and includes wilds, scatters, free spins and three modes of play: standard, flight and run. This action-packed pokie was designed to be entertaining for many hours of play.

Remember not to chase those bonus rounds when they don’t come up on their own, you could drastically decrease your bankroll without any luck unlocking the bonus games. If you feel that you have to experience a particular bonus round, it’s best to enjoy free casino slot games with their bonus rounds than to play with real money.
