By this version, standard slugs (100% power) cannot compete. You must focus on Fusion Slugs. Fusions combine two elements and require matching 5 tiles to fire.

Top-Tier Fusions to aim for:

Slugterra: Slug It Out (often seen as Slug It Out! or Slugterra: Slug It Out 2 for its sequel) is a match‑3 / tile‑matching puzzle game franchise based on the Slugterra animated series. The games combine casual match mechanics with a collectible “slugs” roster, character progression, fusion shots and narrative encounters with series villains. Version numbers around 2.9.8 suggest minor updates to the original Slug It Out! (2014–2016 era) builds rather than major engine overhauls; later, a separate Slug It Out 2 series continued development under different publishers.

Version: 2.9.8
Platform: Mobile (Android/iOS – legacy version)
Rating: ⭐⭐⭐⭐ (4/5)

As a fan of the Slugterra animated series, revisiting version 2.9.8 of Slug It Out! 1 feels like unearthing a classic arcade gem from the caverns. This particular version sits in a sweet spot: it’s after the major bug fixes and quality-of-life updates, but before the game became overloaded with aggressive microtransactions or shifted focus to its sequel.
