Mandy's Wheel

Mandy's Wishing Wheel is accessible from the player's base, on the left of the UI, and offers the player a free random reward daily. Additional spins may be bought for 100 cores each, or acquired by tickets that are rarely dropped by stages or events.

Per spin, the Wheel can possibly give the player:
 * A random 5-star emblem
 * 40 Blueprints
 * 30 Candies
 * 5 Candies
 * 150 Oil
 * 1000 Gold
 * 500 Metal

While the Wheel seemingly offers a 12.5% chance of dropping that delicious 5-star emblem (i.e. every 8 days on average), it is unfortunately a Wheel of Disappointment as the actual drop rate is abysmally low (< 1 in 30); the display is just there to tempt players into wasting all their cores for sweeties. Thanks Mandy, you're such a pal.
