It is brightly coloured, quirky and very dynamic. An upbeat electro-pop rhythm is amplifying the high-voltage action on an unorthodox 4x7 grid with a peculiar number of 127 pay lines. But wait, these are not the entire elements here. There is Respin Insanity actuated with every win and plenty of sticky Multipliers Wild in both base and bonus game, reinforcing the profits and the overall performance of this Highly Volatile online slot with an RTP of 96.01%. The developer declares the maximum game win as 264 040 CAD, or 6601x the total bet, when betting with the max stake of 40 CAD.

Do not hesitate to probe the 777 Mega Deluxe on our page in the DEMO version, and when ready to make real deposits, go ahead and launch the game at any of our partners' casinos (here on display on the right side).

Personal testers’ opinion

  • Holy moly, as much as we love fruits machines - that much we are charmed by the astute and outlandish creations of this USA, Reno, Nevada - headquartered avant-garde Studio. Haters gonna hate, you know, but we also have a say. We strive to stay impartial, so we must give the credit to anyone out there who is forward-thinking. According to us, Crazy Tooth Studio is such. Their 777 Mega Deluxe creation is refreshing, not a reskin! Good enough reasons to check it out and probe its potential.
  • Let's see: the paytable is not generous from 0.25x the total bet (for the lucky 7’s) to 0.10x the total bet (for the orange stars) all for 4OAK on a pay line, the hit ratio is very poor at 16%, and the RTP is just acceptable at 96.10%. Yet, the game successfully creates insane opportunities.
  • The provision board also displays the amounts between 31.75x and 12.7x the total bet for a full screen of all symbols, which is awarded immediately as the Re-spin function needn’t be launched in such cases. During the Re-spin action, it might seem that more spins should be awarded, but it all depends on the positions of the surrounding symbols - they have to make extensions outside the already winning area!
  • Although affluent on promises and potential, this Re-spins rich slot tends to deliver only mediocre rewards during the bonus features. During test sessions, our topmost payoff was 172x the total bet (perhaps due to the small un-retrigger-able number of freebies - only 4). From all the received bonuses, we tallied the average amount of 64x the total bet. Unfortunately, Multiplier x5 is hard to come by, and waiting for the bonus can also be frustratingly over-long.

In summary: 777 Mega Deluxe is not your mundane slot. It is far greater than many conventional Bars/7’s/Fruits games. Beautifully finished and supplied with more than decent rewards. Crazy Tooth Studio went the whole nine yards putting everything on the table: developing a payable slot and great pastime nominee. We encourage sessions with real money (via middle size bets - 1 CAD max to 8 CAD) until 1 bankable Free Spins round. After this, you have to re-evaluate your bankroll status and resolute to play more or walk away for the day. It is not a tailored slot for bonus hunters.

Bonus Features

There are 2 types of Wilds in the game, both of which: Wild and Multiplier at the same time. For both Wilds count, the same traits: 1)substitution (for all but Bonus/Scatter symbol), 2) becoming sticky any time they drop, and 3) the ability to create their own combination (for example, 3 times Multiplier-Wild X2 in the base game on a pay line will pay X2X2X2 the total bet = 8x the total bet).

  • X2 Multiplier is the Wild card during both: base and bonus rounds.
  • X5 Multiplier is the Wild card during only the bonus rounds.

Naturally, you want to see more of these sticky Multiplier-Wilds, as they help best to boost your balance.

Any winning combo automatically triggers the Re-spin function, where the non-winning symbols are locked, and only the winning symbols will spin once more. If the new combos that fall create an extension with the previously locked icons, the Re-spins go on.

Free Spins
3 pink Bonus/Scatter symbols (possible to drop only on reels 1/2/4) will launch the 777 Mega Deluxe FS.
Their number is always 4 and cannot be prolonged. Re-spins are also active here.
