At the start of 2017 there is a Lucky Draw that allows you to get some free goodies.
Next to the icon for the sales at the right top of the screen, there is a new icon for the Lucky Draw. When you click on it, there are three Steps to select possible prizes and afterwards you can make draws from the prizes. This works in a similar way as the Tarot Reading. However the first lucky draw already costs 7 Tokens, the second 12 Tokens and afterwards it costs an increasing amount of Tokens to make more selections. These Tokens can be acquired by completing the Daily Rewards (2 Tokens per day) to a certain level (do not forget to claim them each day) and by topping up a minimum of 1000 gold in the gold store (5 Tokens).
You have to pick 4 prizes from Step 1. The prizes are an Advanced Teleport, 20 Intensity Crystals (I), 20 Intensity Crystals (II), 15 Dragon Scales, 10 10,000 Food items, 10 Intensity Crystals (III) or 3 100 Gold items.
You have to pick 3 prizes from Step 2. The prizes are 40 25,000 Dragon Spirit EXP, 10 100,000 Lord EXP, 10 100,000 Dragon EXP, 7 Intensity Crystals (IV), 10 Purple Scroll Fragments, 20 1,000 Gold, 4 Intensity Crystals (V).
You have to pick 2 prizes from Step 3. The prizes are 15 gold Scroll Fragments, 40 100,000 Lord EXP, 3 Intensity Crystals (VI), 40 1000 Gold, 40 100,000 Dragon EXP.
It is difficult to say what the best prizes are. Not all of them have a direct monetary value, as you cannot purchase them with gold. I went for a combination of the lower level Intensity Crystals, various EXP items and Gold.
Once you selected the prizes you can Confirm your pick (if you don't, all will be reset the next time you enter the Lucky Draw). Once you have done that you cannot change.
The prizes are nice, but you need to spend to get more than one prize and I am wondering whether it is really random (as in you get an equal chance between all prizes, or there is some weighted factor in there, and you are actually more likely to get a prize from the Step 1 selection than from Step 2 or 3).
