There is a treasure box, and you must peek into it to find the gems – this is, in short, story about an online slot Arcane Gems. Adventure, treasure, mystery – all this is in this game because the pirates are sailing around the Mediterranean. Design is pretty neat with the vivid and bright colours, while the music in the background is soft and becomes more intense in the moments when a player wonders what is about to happen next. The RTP and the game's volatility are on an average level – 96.05% and a player gets a chance to bet on a rate of $0.10 on the minimum and $50 on the maximum. The grid has three reels, and five rows with the nine paylines and the winning point are after collecting 3, 4 or 5 identical symbols. The symbols are cards, gems, and the diamond, which is the highest paying symbol and will bring 25x the bet. There are two special features in this game which you can find at Canada online casino – lock mechanics and multipliers. Lock mechanics means that after you land the winning combination, the highest winning symbol will be locked, and all others will respin, and this continues until more high-value symbols land and bring winning combinations. If the reel is filled with these locked symbols, the new feature is activated – multipliers. How many times your cash will be multiplied depends on the symbol locked – the highest paying is again diamond, and it bears 5,625x.
