Join a mediaeval alchemist and try and conjure up a jackpot-winning spell in Convertus Aurum. This 5 reel, 10 payline slot is from Blueprint Gaming and comes with a bonus round that awards up to 60 free spins where the lower value symbols can magically transform into the higher paying gold. Play on all devices from between 10p and £100 per spin.

The setting here is a wooden library packed full of books and bottles of potion. On the reels you’ll see A to 10 royal values as well as sand timers and flasks that pay up to 35 times your stake per payline followed by the scales that offers awards of up to 100 times your stake per line. The most rewarding symbol is the wise old owl. Land 3, 4 or 5 of these in the same payline and you’ll win 5, 20 or 500 times your stake.

The bearded alchemist is the game’s wild. It doesn’t offer any payouts in its own right but it does substitute for all other symbols. The alchemist developers some extra magical powers during the Free Games feature too. To trigger that bonus round, you’ll need to land 3, 4 or 5 of the bubbling cauldron scatter on the same spin. You can then look forward to 10, 15 or 30 free spins.

Every time the wild lands during the feature, all of the A, K, Q, J and 10 symbols all transform into the gold bars symbol which pays 1, 4 or 15 times your stake coins if you land 3, 4 or 5 on a payline. Those number might not be especially large but you can easily land a big cluster of gold bars on a single spin. Re-triggers are possible here too meaning up to 60 free spins are possible.

Convertus Aurum is a simple game. The highlight is the Free Games feature where the wild alchemist can work plenty of magic and turn the base metal on offer from the lower value royal symbols into potential gold. The variance here is in the medium to high range which top payouts of 5,000 times your stake on every spin/free spin.

It’s not the most complex of games by any means but if you like the alchemy theme, then it’s worth trying to magic up some gold in Convertus Aurum. If you want more bonus features, The Goonies (also by Blueprint Gaming) is a must.
