Anyone that has an eye for precision and mechanical engineering will be drawn to the cogs and springs of the BARs & 7s slot. This is a unique three-reel game that can work up a thrilling adventure, despite having only two symbols on the paytable.

The maximum win potential may not be much (40x from any single spin) but in my experience, BARs & 7s have generated wins on multiple paylines, and this isn’t such a rare occurrence.

Theme and Graphics

At first, playing the game may feel like you are playing tic tac toe. I thought it nonsensical to play a slot that only has two symbols, however, that impression went away once I got into the fine details and moving parts.

Wazdan has done a nice job in creating a well-rounded game that is complete with animated symbols and flowing gameplay. The background is a mechanism of turning cogs and traction belts that power bizarre bulbs and coils. In terms of graphic design, the game has it all for a pleasurable slots experience, minus the sound, which I found intrusive and, shall I say, ‘mechanical.’

Extra Features

I didn’t expect to find any extra features in this game. The two-symbol paytable just doesn’t leave any room for a scatter symbol or a wild, and these would have disrupted the concept of the game.

Nevertheless, Wazdan has a standard set of options on its productions that can be utilised in the gameplay.

  • Gamble Feature

    Any winning outcomes can be taken to the belly of this mechanical beast for a game of hit or miss. BARs & 7s pits you against a choice: pick the BAR or the 7s symbol. If your choice matches the symbol that is randomly selected by the game and shown in the center of the screen, your initial winnings will be doubled. Each good guess results in doubling the amount you’ve won insofar.

  • Volatility Selection

    This is part of the game mechanics that you can’t see manifesting on the screen, however, selecting the volatility level does impact the frequency and size of payouts. To change the volatility, press the pulse graph button to toggle between Standard, Low and High.

    For players who are just getting into slots, low variance results in more frequent wins, often consisting of amounts that rank lower on the paytable. High variance is the opposite – wins are sparser but stronger, with medium variance striking a balance between the two.

Bets and Payouts

The game can make payouts across eight paylines. Usually, three-reel slots don’t ring-up wins for a vertical stack of symbols, so I was surprised that BARs & 7s do that for all three reels.

Win outcomes are generated with three matching symbols and with each spin, the reels bring about iterations of these two symbols and blank positions.

Winning one payline with either symbol results in a prize of 1x your bet. The game adds +1 on as the bet multiplier for each additional payline win, up to four. Wins consisting of five, six and eight paylines result in payouts of 8x, 16x and 40x your bet.


All this makes for a rather straightforward game that I’ve come to enjoy playing. Maximum wins of 40x may not be so appealing to players who like high win potential games, but on the other hand, this is an outcome that is more realistic than anticipating a maximum exposure of 5000x or 1000x to hit.
