Released on 11th July, 2018 by iSoftBet, Mystery of Longwei is an oriental-themed slot with a 5X4 reels format. It has a medium variance, and players are treated with a high RTP of 97.01%. The slot game has 40 lines, wilds, and free spins bonuses.


An oriental-theme slot, the game has a serene audio but a lively yet simple tone if a prize is won. It has six high-value symbols, six low-value ones, and three features symbols.

The high-value symbols are:

  • Phoenix
  • Tiger
  • Panda
  • Lotus
  • Koi
  • Golden pot

The three feature symbols to watch out for are the scatter, dragon, and the wild.


Below is the paytable of the slot for the high-value symbols.

Number of Appearances in a Pay Line  SYMBOL
Phoenix Tiger Panda Lotus Lotus Golden Pot
5 1,000 500 400 400 250 250
4 200 200 100 100 75 75
3 50 50 25 25 20 20

Note that the numbers here do not change despite your wager size. Each number is a multiplier, which would be applied to your coin size.

You can set your coin size between €0.01 and €1. For every round, the slot machine would automatically take a bet for 40 lines.

To win, the slot requires that you land at least three same symbols on adjacent reels, beginning at the left most reel. The slot game only pays from left to right.

If you landed three symbols of the Phoenix with a bet of €0.01, your prize is €0.50 (50 x €0.01).


Here are the bonuses found in the online slot machine:

  • Wild – the wild symbol is the block that has the text “wild” on it. It replaces all symbols to help you form a winning line. It cannot replace the Dragon and the scatter. It has no payout of its own, and it does not apply any multiplier if it is used for a winning combo.
  • Dragon Symbol – this one only appears on the first reel. If it does, it will trigger up to four Colossal Spins. A colossal spin means that some symbols occupy up to four slots on the grid. They are giant symbols that can make it easier for you to form a winning line.

NB: During the colossal spin, the dragon symbol is going to drop one slot at every spin. The reels will keep re-spinning, free of charge, until the dragon symbol is gone.

    • Scatter – the scatter symbol is the Chinese castle. Landing three to five of this on one spin, anywhere on the grid, will trigger the free spins bonus. You can win between 10 and 30 free spins.

During the fee games, the slot would use the same bet as what triggered it, but at no extra cost to you. You cannot re-trigger free games. On this round, the high-value symbols are colossal and can appear between reels 2 to 5.


The slot game is a great choice for players who are looking for a typical set-up like wilds and scatters.

The colossal symbols are a fresh innovation, and the bonus Dragon re-spin is a great addition to improve your odds of winning. Overall, we would rate this with 8.2 stars out of 10 because of its simplicity, straightforwardness, and feature symbols.
