Avalon is the legendary island where King Arthur's sword Excalibur was forged. Inspired by this legend, the tone of the Microgaming slot Avalon is characteristically mediaeval. The reel icons feature symbols such as a chalices, crowns, jewels and high cards. The background music is quite chilling and makes you realise the importance of the Lady of the Lake in the game.
The Avalon symbol is a wild and adds a multiplier when it completes a win; however the Chest icon also acts as a wild in the free spins round. To get to the free spins bonus round, three of the Lady of the Lake symbols need to be rolled. In this round, there are twelve spins, which are subject to multipliers of between two times to seven times. The beauty of this bonus round is that the multipliers apply to the top prize of 3000 coins and also can be retriggered.
In addition to this, wins activate the gamble feature. In this bonus round, you may double your win by guessing the colour and then quadruple it by guessing the suit of a face-down card – it's that simple.
Having been around since 2006, Avalon has maintained its allure which means that it must be doing something right.
