Karma

 was formerly a type of Currency in The Sandbox Evolution.

Uses
Karma was used to unlock some elements, playable heroes, enemy bosses and occasionally special campaigns. Karma was rarer than Mana.

Acquiring Karma
You could acquire Karma through the following methods:
 * Completing some Campaigns.
 * Rewarded randomly at the end of some player-created levels.
 * Sometimes from watching video adverts.
 * Part of the daily login rewards.
 * Purchasing from the in-game store with money.

Trivia

 * Karma was only available in the mobile version of the game. It never appeared in the PC version.
 * Karma was removed from the mobile version of the game to bring it in line with the PC version of the game, for balancing reasons.
 * When Karma was removed from the mobile version, the Karma on player’s accounts was converted into Mana at a double rate.
 * All the emelents that we’re previously purchasable with Karma, can now instead be bought with Mana or unlocked with a premium account.
