The balls

Breaking pegs and smashing bugs fills your steam gauge. When it's full, pick a special ball for one of your three slots. Each one is used up when you fire it.

The the ivory ball, rendered in brass, iron and glass
Always loaded

The ivory ball

Free and unlimited. Every shot starts here.

  • Damage 1 per bug
  • Cost Free
  • It bounces off brass pegs and cracks copper ones.
  • If it reaches the castle it rolls along the wall and hits the beetles up there.
The bomb, rendered in brass, iron and glass
For crowds

Bomb

An iron shell with glowing seams and a lit fuse. It blows up on the first bug it touches.

  • Damage 2 to everything nearby
  • Unlocks Level 2
  • Save it for when beetles bunch up, especially at the front.
  • The blast cracks nearby copper pegs too, which opens up the board.
The splitter, rendered in brass, iron and glass
For a spread-out board

Splitter

A brass ball scored into three pieces. On its first peg it splits into three balls that fan out.

  • Damage 1 per ball
  • Unlocks Level 7
  • Aim it at a peg near the top so all three balls have room to work.
  • Great against fast beetles scattered across different lanes.
The iron, rendered in brass, iron and glass
For armor

Iron

Heavy, riveted iron. It doesn't bounce off beetles, it goes straight through them.

  • Damage 2 per bug
  • Unlocks Level 13
  • Line up a row of bugs and it hits every one of them.
  • Two iron hits crack an armored beetle.
The phase, rendered in brass, iron and glass
For bugs behind pegs

Phase

A clear glass ball with a ghost of light inside. It drifts through pegs and only touches beetles.

  • Damage 1 per bug
  • Unlocks Level 15
  • Use it when a beetle is tucked behind a wall of pegs.
  • It still bounces off beetles, so it can hit more than one.
The tar, rendered in brass, iron and glass
For buying time

Tar

A black ball dripping with tar. Any beetle it touches gets gummed up and skips its next move.

  • Damage 1
  • Effect Skip a turn
  • Unlocks Level 19
  • Tar the beetle about to climb the castle and it stays put.
  • Beetles that were about to step into a tarred bug's spot have to wait too.
The tesla, rendered in brass, iron and glass
For groups

Tesla

A glass sphere around a copper coil, crackling with blue sparks. Each hit sends lightning to nearby bugs.

  • Damage 1, plus lightning
  • Arcs 2 bugs per hit
  • Unlocks Level 21
  • The first three bugs it hits each throw lightning at the two closest beetles.
  • Fire it into a cluster and watch it chain.
The rivet, rendered in brass, iron and glass
For a battered castle

Rivet

A brass ball studded with rivet heads. When it lands on the castle wall it patches the damage.

  • Repairs 3 castle HP
  • Unlocks Level 25
  • Aim it so it falls all the way to the wall.
  • It rivets a brass plate onto the castle where it lands.
The boss-breaker, rendered in brass, iron and glass
For the big one

Boss-breaker

Blued steel, a brass cross and heavy spikes. It hits harder than anything else in the game.

  • Damage 3, or 6 on a boss
  • Unlocks Level 27
  • Hits on the boss's gears do double damage, so a boss-breaker that lands there does 12.
  • Against regular beetles it still does 3 damage, so it's never wasted.
