When players first load up the Slammin 7s online slot by iSoftBet, it's going to look like a five-reel video slot. However, it's actually more along the lines of a three-reel classic slot with video slot features. The graphics in this game are very niche, and while they aren't great in the sense of how you'll see some games with 3D graphics or custom animation, they are perfect for the gameplay that this title offers. This is a somewhat atypical game, and you may need to actually play the demo a few times to get an understanding of the gameplay.

Game Layout

There are essentially two parts to the game layout that you need to pay attention to. On the left, you will see three rows of three symbols, though they go upward in sort of a diagonal slant. This works exactly like three reels in a classic slot in that you'll be making winning combinations from left to right. However, it's also an "all ways" format game, which means there are 27 ways to win. Get at least one of the same symbol on all three reels, and you win no matter which positions they are in.

Betting is based on sets of 50 coins, and the coins start at $0.01 for a minimum bet size of $0.50 per turn. They also run up to the $0.50 level, so you can bet as much as $25 per turn if you are so inclined.

The Multiplier Symbols

On the right-hand side of the game's layout, you'll see two extra symbols that flip around during each spin as well. These two symbols are the keys to a number of features in this game, the first of which are multipliers. If one of those two bonus feature spots shows a multiplier symbol like x2, x5 or x10, and you hit a winning combination while it's showing, then your total win is multiplied by that factor. This leads to chances for some pretty significant wins, even with the lower-end payouts, which is a pretty value-packed opportunity.

Bonus Wins

Another feature symbol you can see pop up is for bonus wins, and they look like +25, +50, +100 and +500. The basic idea is that these wins are added to your total payout, but only if you also hit a winning combination. This means that if you won 50 coins on the reels and picked up a +100 symbol along with that, then you would get a total payout of 150x. This is another cool and fairly innovative way to give players extra value on the reels, and these wins can combine with the multiplier symbols to give you even larger pays.

The Re-spin Feature

Finally, there's a re-spin symbol that can show up on the two slots on the right as well. If you get a winning combination when this symbol is up, then you get a set of up to five free re-spins, all of which have a 2x multiplier. This multiplier stacks with the multipliers from the feature listed above, and that means you can end up with multipliers as large as 20x overall. That's a pretty big deal, and it's worth paying attention to because you rarely see multipliers that big.

Winning Combinations

All winning combinations in this game are based on three of a kind wins. Three of the Slammin 7s symbol earns 300x. Three of the triple bar gives you 200x, three of the double bar is good for 150x, and three of the single bar awards 100x. These symbols are obviously a throwback to older, classic slots, but the pace of the gameplay is more like a video slot.

You'll find a ton of different seven symbols in this game, and it might seem tricky to try to keep up with which symbols pay which amounts. They've actually made it pretty straightforward if you know the pattern. There are three flaming seven symbols, and all of them pay 30x. There are also three non-flaming seven symbols, and they pay 10x apiece for three of a kind.

It's possible to get a top jackpot of up to 50,000x if you pick up three of the Slammin 7s symbols with a +500 bonus win and a 10x multiplier during the re-spin feature. It'll be 25,000x if you hit that combination of symbols during normal gameplay without the re-spin 2x multiplier.


Slammin 7s is a very fun concept for a slot, and the fact that it combines a classic slot layout with video slot action will make it appeal to players who typically like games from each subgenre. We would have liked to see somewhat better graphics, but we aren't certain if that would have taken away from the super strong gameplay here. In any event, it's a very solid game that shows iSoftBet is capable of going in many different directions with their titles.
