Boosters

What each one does, what it costs and where it helps

A booster is a bought edge for one round. There are two kinds: “Take along” and “On the belt”.

  • Pepper Bomb
  • Long Minute
  • Running Hot
  • Rainbow Potion
  • Double Batch
  • Clock Potion
  • Hammer
  • Whirlwind
  • Magnet
  • Thunderbolt
  • Mega Bomb

What suits which goal

Mega Bomb: Fits any goal

Where boosters do not work

  • Boosters do not work in arena fights.
  • There are no boosters in the daily challenge: everyone gets the same board and terms, and a bought edge does not count there.
  • “Thunderbolt” works only against a guardian.

Mega Bomb

Does 80% of the level goal in one blow.

You can buy it, or put one together from shards: 5 shards make a mega bomb. No luck involved: shards come by rules.

  • The first win over each guardian gives a shard.
  • A first pass of a level with three stars: one in 8 gives a shard.
  • 3 stars in the daily challenge: a shard, once a week at most.
  • Place 3 or higher in the arena week table gives a shard.

A level passed with the Mega Bomb earns one star.

Samples and gifts

  • On the level that unlocks a booster you get one sample.
  • No sample for: Mega Bomb.
  • Starter pack: 120 sparks and a stock of boosters — Pepper Bomb, Long Minute, Running Hot. Given once, for free.
  • Boosters also come in the daily reward.
  • Stuck on a level? The game helps. After 3 failures in a row Blub gives you the best booster for the goal.
