Every round of this Blueprint Megaways game opens on five dynamite sticks and a choice: keep the 8 to 20 spins they give, or gamble them on a wheel for up to 30. I gambled six times, won three and lost three, and one losing bet on 20 still paid out 12 consolation spins.
Blueprint Gaming is a software maker. It's been creating games for internet casinos, and with too much leisure on my hands and no other slot in the fire pit, I chose to give their slot Diamond Mine Extra Gold All Action a go. It shares the Diamond Mine name with Diamond Mine Megaways and Diamond Mine Extra Gold.
Diamond Mine Extra Gold All Action is a 6-reel Megaways slot with up to 117,649 ways, 97,03% RTP and a wager tier spanning from 20 to 2,000 credits, and this is an All Action slot with no base game. Each reel holds 2 to 7 rows, so the ways count moves between 324 and 117,649 from spin to spin. It arrives with a pair of mechanics which I will analyse further beneath. A 4-position horizontal reel runs above reels 2 to 5. But to be frank, the game doesn't truly require a user manual. Over 58 rounds at 20.00 each I wagered 1,160.00 and won back 1,106.60, which took my balance from 980.00 to 926.60.
Symbols on the reels comprise the usual low returning 9 to A royals, as well as 4 high worth symbols in the shape of lanterns, pick & shovels, prospectors, and diamonds. The latter award 0.5x for 6 of a kind, and the Dynamite Wild appears on the horizontal reel solely. Six prospectors pay 0.075x the stake, six lanterns or six pick & shovels pay 0.02x, and six of a royal pay between 0.008x and 0.0175x.
Final Minty Score: 56 of my 58 rounds paid something, and 46 of them returned below the 20.00 they cost. The session returned 95.4% against the stated 97.03%, and the balance only got past its 980.00 start after round 32 pushed the multiplier to x14 and paid 356.80.
Every round activates the Free Spins feature, with a dynamite selection of 1 of 5 sticks granting 8 to 20 starting spins. TNT barrels can also land on any reel during a free spin, and once the reels stop they all reveal the same symbol. Any winning symbols landing on the reels are removed. Fresh ones drop in and the Win Multiplier climbs up by +1 on every winning cascade, while 3 or 4 scatters on the horizontal reel give +5 or +10 free spins, and the feature finishes when all spins have been used. The multiplier does not reset between free spins, and in my best round it reached x14 on the way to a 356.80 win, or 17.8x the stake.
If the player doesn't take the spins, the Extra Gold gamble is started. Gambling 16 spins or fewer and losing ends the round with no spins, while a higher count that loses drops back to 8, 12 or 16 free spins. A green/red wheel is turned for extra spins, up to 30. I took the gamble 6 times and won 3, reaching 20, 24 and 30 spins, while a losing gamble on 20 left me with 12 consolation spins.
Diamond Mine Extra Gold All Action is a tiring slot in several ways, and the returns are really disappointing and the Megaways layout has been overdone by this stage.
