Avalon Slot

Avalon SlotAs claimed by the legendary 15th century Malory’s book, the idolized sword Excalibur was bestowed to King Arthur by the Lady of the Lake (a chimerical woman with enigmatical abilities) at Merlin’s appeal - Arthur’s trusted mentor. Most stories agree that with Excalibur, King Arthur withstood and ruined Mordred - his nephew, getting himself mortally wounded in the battle.

Afterwards, Arthur is taken back to the mystical isle of Avalon, and the sword is conveyed back to the lake. In the end, the conflict between the Knights of the Round Table led to major riots, causing the death of King Arthur. 

Microgaming’s developers successfully enlivened the great legend by releasing the 2006 Avalon slot machine.

This slot has High Volatility with an RTP of 96.01%. The RTP allows obtaining a positive mathematical expectation of winning in the casino. Test the Avalon slot machine in the free DEMO mode right here on our site. No login is required.

Personal testers’ opinion about Avalon slot

The slot feels outdated by today’s norms with its unimpressive graphics and sounds, plus the gameplay is rather routine than exciting. However, despite its age, the machine is still loved by some Microgaming fans and remains often demanded in many casino lobbies.

  • The paytable (except for some 5OAK) is not super generous, explaining that the payouts here are commonly small.
  • The volatility of the game is high. For example, it gets an index of 7.5 (from 20). 
  • For the bonus money wagering, this slot scores only - 3.97 points (out of 10). Due to this low rating for completing the bonus requirements, the Avalon slot machine is unsuitable for the bonus hunters.
  • We established the frequency of any hit (winning) is 26.33%.
  • The division of the prize pool is 40% reserved payouts for the bonus round and 60% for the usual spins.
  • According to our statistics, the Free Spins are triggered after every 193rd spin (0.52%) under the desired middle line. 
  • The absolute maximum payout obtained during the tests was 724x.
  • The average winning from the bonus round was 61x.

Review and recommendations by the testing team

In the crowd of the myriad highly appealing online games with some sensational features, this archaic Microgaming slot no longer stands a chance to compete for the gamblers' attention.

During the base game, the winnings are mostly small or just below the bet. 

  • There are practically no large payouts.
  • Some significant winnings we had in the main game: were approximately 40x the bet.
  • The player’s tactic should be: to wait for a bonus round as long as the slot holds the balance.
  • The most optimal action will be playing at a low denomination and the maximum number of coins, which will keep the balance at a decent level till launching the Free Spins.

With the help of Wilds and Multipliers, your balance has a good chance to increase during the Free Spins.

  • Do not get greedy- remember that after the Free Spins round is best to finish your session.
  • In the bonus game: Besides the super-maximum of 724x the bet achieved once, other solid winnings were 400x and 450x bets, but the average was around 60-65x.
  • Here it would help if you were attentive to the fact that the Free Spins are not often initiated. Certainly, the bonus round will be activated more frequently if you play at low stakes. So, betting small can increase the probability of launching the Free Spins. 
  • It is regular to get a high multiplier in the bonus game. We rarely got a multiplier less than x4 during our tests. Combination with 2+ Wild symbols and high valued icons with 4x+ Multiplier can bring substantial payouts, making the bonus round worth waiting.
  • If the slot doesn’t trigger a bonus round and doesn’t hold the balance, you better leave it after 150-170 spins.

You should avoid using the Gamble Feature!

We advise you to take the risk only if the payout you are ready to lose is less than the current bet. Even then, guess the colour of the card, where the chances of winning are 50%. The probability of winning, guessing the card suit is only 25%, so we absolutely do not recommend that option. During the gambling function, you should try to uncover the sequence with which the cards are opened. According to our observations, the same suit gets opened at least twice in a row. If you managed to guess right and received an amount that exceeds your bet, it is best to stop gambling for the round.

How to win at the Avalon slot machine? (Conclusion)

  • Be circumspect with your capital and test the game in the DEMO mode upfront.
  • We do not recommend this slot for playing with bonus money and fulfilling the wagering requirements, as the slot is not keeping the balance well and is not showing significant potential in the base game.
  • We do not recommend this game to the players who want to win an epic amount of money.
  • We do recommend Avalon slot machine, however, to play with real money, but cautiously and only:
  • 1) If you find a big and famous casino, the prize pool has a better chance to be accumulated. 
  • 2) If you have sufficient bankroll. It is wise to start playing with small stakes and to have at least 500 total bets on the balance. We suggest picking 1/500 of your balance as a bet per single spin.
  • 3) If you can manage to play sessions with around 150 - 170 spins till receiving the bonus game. (The important fact here is that it takes 125 to 170 attempts to come to the Free Spins on average. Considering this number of necessary spins, you can adjust the value of your bets and have a higher stake once you are rewarded with the bonus round). If free Spins are not rendered within this time, you better change the slot, as this shows a ‘cold’ slot syndrome.
