Simplicity is beauty in this slot. A boiled down, well built three-by-three slot experience that is only really let down by the lack of a published RTP.
777 Gems is Booongo’s contribution to the world of minimalist slots. Rather than going with fruit machines as their base inspiration they mixed up a few classic symbols (bars, bells, and sevens) with the post-bejewelled default of precious stones.
That’s all there is to it, because 777 Gems' whole deal is do as little as possible, and do it well.
The graphics are lovely, a slick light show of red on a black background. The animations are smooth and full, but not over the top for a game so basic, with a fairly typical set of winning animations that highlight what needs highlighting but do not go over the top.
The simple music free sounds add to the stripped down atmosphere that the slot is attempting to generate.
All in all, it is a textbook case of designed simplicity.
The gameplay for 777 Gems is also as simple as they come. A three by three grid which pays out for any three symbols in a straight line on all three reels. This means there are five win lines total – the three horizontals and the two diagonals.
If you land nine identical symbols, filling up all three reels, then the slot not only pays out on all five winlines but also offers a multiplier of two on all winnings for that spin.
There are no special symbols, bonuses, or free spins in 777 Gems.
The return to player of this game is not provided by the publisher. This is always a bad sign. While some sources describe the return to player as "high", none put a number on it. We recommend avoiding slots where this information isn’t available.
The site we tested offered a range of best that went from $/£/€0.10 per spin, up to a maximum per spin of $/£/€100.00.
The volatility of this game is high. See our preferred strategies to get a sense of how we like to take advantage of that fact.
777 Gems is another excellent minimalist slot. Providing you do not require bonuses and flashy animations from your slots, this could be right up your alley.
We really like the game’s high volatility but are put off a bit by the lack of a published return to player.
