Wheel of Fortune

"Wheel of Fortune" appears as a floating option when you hover over "Inventory". Click on it once it pops up.

You might have extra card duplicates when the cards are seduced to 5 stars. In this case you can turn these extra duplicates to the Magic Dust. Use the Magic Dust to play the Wheel of Fortune to get unique cards and other cool prizes.



A brief history
Wheel of Fortune (WOF) version 1 lasted for a few weeks. It gave stuff you see on the wheel at equal chance (1/12) of the time. This led to more veteran players accumulating large amounts of gold coin, rubies as well as silver and gold boxes - allowing these players to win daily tournaments easily, win event tournaments, and obtain perfect stones for their decks. Around this time there was a glitch which gave players more dust than expected when they dusted their cards.

WOF version 2 had adjusted probabilities for the wheel. About 50% stones, 20% boxes of materials etc. Rubies and gold coin dropped rarely - about 1-2%. Silver boxes and gold boxes were also rarer than version 1. Mathematically, players get much less energy or gold coin in version 2 compared to version 1.

WOF version 3 is the current version. The wheel increases with level with every 3 spins, forcing you to move to the top lvl 5 if you want to use up excess dust. Probabilities of drops seem to match version 2. Mathematically, players get even less energy or gold coin, which is only partially compensated by the savings in gold coin from getting a higher level stone.

Heat Levels
Each 3 times you spin the wheel, its "heat level" increases, and you get more chance for better prizes :

You need 16 Polished stones to make 1 Pure stone, so the dust cost is the same for all heat levels, except that gold needed is waived from level 3 and higher. After 24 hours, the heat level is reset, and the counter only starts again after at least 1 spin (like bronze boxes, as the timer only starts after being opened).
