Introduction
Mystery Apollo II is an online slot developed by Apollo Gaming. It is played on 3x3 reels with 27 paylines that pay from left to right. The simple format comes packed with features, including a gamble option and a mixer symbol that triggers one of four outcomes: the joker, which acts as the wild symbol; a multiplier, which can appear multiple times with different values that accumulate; a mystery symbol that pays a multiple of the bet; or a respin symbol that triggers one free game.
The mystery symbol can be the top-paying symbol; however, the regular paying symbols begin with the joker as the top-paying symbol when you land three in a row. Next up is the double 7, which shares its value with the watermelon. Next on the paytable are the grapes and bells, followed by the plums, oranges, lemons and cherries.

Theme, graphics and soundtrack

The soundtrack is mysterious to match the theme. When winning lines or features land, the player is treated to a classic electronic tune from retro land-based machines of the 70s.

Mystery Apollo II review: our verdict
This is a retro slot with a twist from Apollo Gaming. The layout and symbols are reminiscent of a classic fruit machine; however, the designer has levered in plenty of extras involving multipliers, wilds, free games and mystery prizes.
The RTP is a little disappointing but was around average when the game first appeared. The variance is medium, which will appeal to plenty of players. The decent bet spread may even attract high rollers, although the maximum payout will not necessarily appeal.
