Diamond Mine All Action Megaways™ is a 6 reel slot from Blueprint Gaming. This game is the 3rd in the series of Diamond mine and once again runs on the Megaways™ mechanic that is under license from Big time Gaming. With Megaways™ in place it is possible for this slot to generate up to 117,649 paylines on any spin of the reels. 

As this is an All Action slot there isn't any base game present, this means players are presented with a total of 5 stakes to choose from that will take them straight to the bonus round. The lowest stake available to play at is €20, and the highest possible bet is €100. 

DIAMOND MINE All Action Megaways™ SPIN SELECTOR

After you have chosen the stake that you would like to play at, you will then be taken to a different screen and invited to choose from one of five detonators. Having chosen your detonator it will then explode to reveal the amount of free spins that you can begin the bonus round with.

Players may already be familiar with this gamble feature as Blueprint included it in Diamond Mine Megaways™ Extra Gold. Through the use of this gamble you have the opportunity to take the free spins you have already been awarded and gamble them up to a possible 30 free spins. 

Depending on how many spins you selected through the detonator will determine where you start on the gamble ladder, which you can see at the top of the screen. Below we have listed the possible outcomes that you can face. It should be noted that you do not have to gamble, and you can take your spins and head straight to the bonus if you wish. 

• 12 Spins - Gamble to win 16, lose and receive 0. 
• 16 Spins - Gamble to win 20, lose and receive 8.
• 20 Spins - Gamble to win 24, lose and receive 12.
• 24 Spins - Gamble to win 30, lose and receive 16.

DIAMOND MINE ALL ACTION MEGAWAYS™ FREE SPIN FEATURE

The bonus round begins with a sight that all Megaways™ players will have seen before. You will have a multiplier in place that will start with a x1 value, and for each win that drops in on the reels, or you receive through a reel cascade, the multiplier will increase by a further x1 in value. As there is no limit as to what this may reach it as classed as an unlimited multiplier. 

It is possible to receive extra free spins through a re-trigger, and for this to take place you will need 3 or 4 scatters to roll in on the upper reel. You will be rewarded with 5 extra spins if 3 scatters appear, whilst 10 spins will be added to your total for a 4 scatter re-trigger. 

DIAMOND MINE ALL ACTION MEGAWAYS™ MYSTERY SYMBOL

Diamond Mine was the first Blueprint Megaways™ slot to feature the mystery symbol, so it was always going to make an appearance in this version of the game. For those who are not aware of it, the mystery symbol can land multiple times on the reels, once the reels have stopped spinning then the mystery symbols in view will all transform to the same randomly chosen symbol from the payable.

There is always big win potential in our opinion with any Megaways™ slot that features this symbol, with you having a particular high chance of hitting something huge if you can land a large amount of mystery symbols when you have a high multiplier in play. 

Diamond Mine All Action Megaways™ is the second slot in this series of games after Blueprint released Buffalo Rising All Action Megaways™ in January 2020. We've said in previous reviews that Diamond Mine is Blueprint's most successful and played Megaways™ title to date, so it came as no surprise that it has received an All Action upgrade.

How long these All Action slots will be around for nobody quite knows. The UKGC have recently stated ( February 2020 ) that they will be looking in to capping online casino games at a maximum stake of £2, so this would spell the end for these style of games for certain.

It's always a mixed reaction when these games are released, so check it out and see what you make of it. We rarely received our stake back during our testing , but you have better luck than us.
