Big Boss Bug

Simian Spark

Raise a tiny champion in a kid's bug cage, and watch it fight its way to the top.

Pick one of 28 real-world bugs: rhino and stag beetles, mantises, tarantulas, scorpions, a giant centipede and a Japanese giant hornet. Your bug trains while the neighbourhood kids cheer, and it keeps getting stronger while the game is closed.

  • Tap your bug to cheer it on and chain combos for bursts of training
  • Upgrade your gym: training stations, a Coaching Desk for automatic sparring, snacks, and the Champion's Regimen
  • Teach techniques, pick perks, and decide when your bug unleashes its signature move
  • Climb six leagues from the Rookie Circuit to the World Championship, then defend your titles
  • Special challenges, surprise challengers, random events and weekly seasons that change the rules
  • Recruit a stable of fighters and start new championship cycles for permanent Legacy upgrades
  • Every fight plays out in 3D with live commentary and an over-excited announcer, or skip straight to the result
  • Built for phones as well as desktop, in English, French and Spanish

Train. Fight. Upgrade. Become the BIG BOSS BUG.

Disponible en français. Disponible en español.
