Hot 81

Hot 81 looks like a vintage jukebox and plays like one of the simplest slots around: four reels, three rows and 81 ways to win, with every win requiring the same symbol on all four reels. Bars, bells, cherries, oranges, lemons and lucky 7s fill the grid, and the star is the prize symbol – a screen full of stars and wild stars pays 81,000 coins. The wild star also converts every symbol beneath it on its reel into a wild. There is no scatter and no bonus game, only a card gamble. Low volatility, a 96.78% RTP, stakes of €0.10 to €10 and an €8,100 maximum win make it a calm, steady choice for retro fans.

The reels sit inside a jukebox-style cabinet that recalls the fruit machines of old bars. The soundtrack changes tone on every win, and winning symbols animate.

Lucky 7s, bars, bells, cherries, oranges and lemons make up the paytable, paying from 10 coins (cherries) to 500 coins.

The ways cannot be changed, so the only control is the stake – 10 to 1,000 coins – set with the bet button; auto start is also available.

The 4x3 grid gives 81 ways to win. Matching symbols must appear on all four reels from left to right, in any row. The star is the top symbol, worth 1,000 coins for four, and 81,000 coins when stars and wild stars fill the whole screen.

The wild star substitutes for every symbol, and all symbols below it on the same reel turn into wild stars too, opening up several ways at once. There is no scatter or free spins round.

After a win, the gamble game offers to double the amount on the right colour or quadruple it on the right suit.
