A hot air balloon, operating as Otto's Lotto, can be seen serenely floating between the Main Island and Distant Marsh in the Archipelago. Selecting the balloon will offer the player several options, the most important being the lottery itself. Going to the balloon can also be done through the button. This button's display will always toggle between a Gem, a Gift Chest and a Five-Card Pack.
Otto's Lotto most important function is watching advertisement videos in exchange for a chance at spinning the lottery wheel in order to win various resources. There are five different wheels, offered in random order after every spin, that determine which prizes are spun for. Each prize wheel is divided into five sections, with each section representing a different prize. The prize sections vary in size, giving greater chances of getting certain prizes while decreasing the odds of getting others.
On some occasions, the Lotto will offer higher amounts, usually double, for a particular type of reward. On other occasions, usually during the period of time a large event is ongoing in the game or a Divine Island is visible, Otto's Lotto may have on offer items related to said events, such as Divine Tickets.
After accessing the balloon, pressing the button under the representative wheel will play a video and then the game will automatically spin the wheel. When no videos are available to watch, the notice will be shown under the same wheel. After the first spin, the player can then watch more videos through the button. If a video has been watched, but, for various technical reasons, the wheel has not been yet spun, the button for watching a video is temporarily replaced by the until after the wheel is spun.
The wheel ratios are as follows:
The probability is calculated as follows:
Each wheel can be divided, imaginarily, in 30 equal parts, separated by gray circles on their edges. One fraction represents 1/30th of the whole wheel, which is, approximately, 3.3% of it. In order to calculate the probability (%) of receiving a certain prize, one must look into how many parts of 30 the prize falls into and translate it to parts of 100. Example: on Wheel 1, a Fury Essence is one of the rewards offered. Its fraction, shown in red, takes 1.5 of the 30 parts. It can be translated to parts of 100 or percentage with a simple cross-multiplication, resulting in 5% (100*1.5/30=5).
Some values have been rounded for practical purposes.
Otto's Lotto Week
Otto's Lotto Week is a time-limited occasion, usually lasting a week, in which each wheel spin has a chance of giving 1 Dragon Piece for a certain Dragon. During this week, the Dragon is also obtainable through promotional card packs in the Main Shop. Whenever Dragon Pieces for a Dragon are available in the lottery, the icon, with the Dragon's image inside it, will be displayed above Otto's Lotto. The button's display will also toggle between the Dragon's image in addition to the regular prizes.
|16-22 July 2018||Ace Dragon|
|10-16 September 2018||Cheerleader Dragon|
Aside from the lottery, videos can also be watched in order to receive a Gift Chest or/and a One-Card Pack. As the chest is the same one from the Enchantment League menu and the pack is the same one from the Main Shop menu, a 6-hour period of time and a 12-hour period of time, respectively, must pass before another Gift Chest and another One-Card Pack, respectively, can be obtained in exchange for watching videos. During the period of time any of the aforementioned items are unavailable, the respective shops can be alternatively accessed from here through the button under the snapshots of said items.
Additionally, the player can temporarily access shops which have items on sale. At the bottom of the screen, the player can navigate through these shops and then access any of them through the button.
