Tier Incremental

Tier Incremental is a fishing-themed idle incremental simulator on Roblox by Vertus studio, where the goal is to reach the highest Tier possible by fishing for resources, upgrading stats, and rolling Runes for passive stat multipliers. The game sits in the incremental simulator micro-genre alongside titles like Fat Per Step and Run on Acid, distinguished by its fishing theme and rune randomization layer.

The core loop is straightforward: fish to earn currency and experience, spend those resources to Tier Up your character, and roll Runes from a randomized pool to apply passive boosts to all your stats. Each Tier Up raises your power ceiling, unlocking higher stat caps and pushing your position on the server leaderboard. Rune rolling adds a secondary grind layer - players re-roll to chase higher-quality passive modifiers that stack and compound as tiers increase.

The leaderboard competition takes place within small servers, so climbing to the top rank is a realistic goal rather than a distant endgame. Potions temporarily or permanently boost progression speed. Vertus studio released the game in October 2025 and has continued with periodic updates into 2026.
