Play Triple Rainbow 7's for Free

Naturally, with its single payline and retro format, Triple Rainbow 7’s is not a hugely complicated game to get to grips with. The slot can be played with one or two initial coins – with the sizes of these coins ranging from $0.10-$10 – but greater prizes await when you choose the latter option.

Indeed, when playing Triple Rainbow 7’s with one coin, the maximum jackpot players can achieve is 1,500 coins. When playing with two, however, this amount does not merely double to 3,000 coins as you’d expect, but is boosted further to 4,000 coins with all smaller payouts being similarly enhanced.

Payouts in the game are typically awarded for matching any three identical symbols on the central payline, but players will also receive smaller prizes whenever a rainbow seven icon appears and when any combination of three different coloured sevens features across the slot’s middle row.

While we’re all for consistency in a slot machine, when your sole thematic concept revolves around the number seven, we think it might be time to start thinking outside the box. Unfortunately, that’s not what’s happened with Triple Rainbow 7’s as, despite the game technically featuring six different symbols, each and every one of them is simply the number 7 decorated in a different set of colours.

In order of ascending value, these symbols go green, yellow, blue, purple, red and then finally the game’s titular rainbow 7 icon, and while this last wild symbol does at least stand out from the rest, the overall visual impression of the slot is lazy and lacklustre. Couple this with the garish rainbow background and retro bubble text and it basically looks like something from a child’s colouring book.

As with all of WGS Technology’s classic slot machines, Triple Rainbow 7’s doesn’t feature anything in the way of unique audio, with the standard bank of casino sound effects used to underscore the game. These include bleeps and whirs when the reels are spinning and the usual winning payline noise, but in truth there’s nothing particularly unique about either the game’s graphics or sound.

While not boasting any bonus features per se, Triple Rainbow 7’s does offer something different from a lot of classic slot machines in terms of how its payouts are structured. As touched on above, the rainbow 7 icon is the main player here, as not only does it trigger the slot’s maximum jackpot, it also substitutes for other symbols to award 3x or 9x prize multipliers for any regular winning lines.

While this helps improve the game’s return to player statistic and reduces the overall variance of the title, players can also benefit from a mixed sevens payout award of 5x their bet. This bonus win is triggered whenever three different coloured sevens appear across the game’s central payline, meaning whether you find a row of identical sevens or a mixed bag, you’ll still walk away with a win.

Beyond that, there’s really not much to Triple Rainbow 7’s. All action in the game is confined to one screen with no hidden bonus rounds and winnings cannot be gambled after a spin, making it an exceptionally straightforward machine. While this may be enough to hold the attention of retro slot purists, however, today’s modern breed of player tends to demand something a bit more complex.

While it’s obvious that the designers of Triple Rainbow 7’s have prioritised simplicity above all else, the game lacks the punch of other retro slots in the WGS Technology catalogue. The various payout awards will at least keep players’ winnings ticking over at a steady rate, but all in all there’s not much to capture the imagination and the colour scheme is more nauseating than it is attractive.
