Here’s a review of Slugterra: Slug It Out! version 2.9.8 (often referred to around the “298 update” by fans), written from the perspective of a returning player.
Performance Optimization: Streamlining the match-3 engine for smoother "slug-slinging" action.
Re-downloading: If you previously owned the game, it may still be available for download through your purchase history on the App Store or Google Play.
