What is IDLE BOSS RUSH? 

IDLE BOSS RUSH is an incremental idle game developed and published by Irid Games, released on September 29, 2025. The game combines active and passive gameplay, allowing players to progress even when not actively playing.

In IDLE BOSS RUSH, you defeat massive bosses and transform a barren camp into a thriving kingdom. Players manage resources, upgrade buildings, and assign advisors to unlock unique item effects and synergies. The game also features BOSS RUSH challenges, offering permanent bonuses for completing extra-difficult encounters, making it engaging for both casual and dedicated players.

How Long is IDLE BOSS RUSH? 

The time it takes to complete IDLE BOSS RUSH varies based on your playstyle and objectives. Here’s a general breakdown:

• Main Bosses Completion: Approximately 3 days to defeat all primary bosses.
• All Achievements: Around 2 weeks to unlock every achievement.
• Maxing Out Content: Achieving full progression, including obtaining all pets and completing optional content, could take several weeks or more, depending on your dedication.

These estimates are based on player experiences and can vary. For instance, one player reported completing the game in about 5 hours, while another mentioned it took them 25 hours to finish and complete nearly everything.

IDLE BOSS RUSH Chapter List

IDLE BOSS RUSH doesn’t follow a traditional chapter-based structure. Instead, players progress by defeating a series of increasingly challenging bosses. Each boss introduces new mechanics and synergies, contributing to the game’s incremental and idle nature.

The game also features a Boss Rush mode, which becomes available after defeating a specific boss. In this mode, players face a sequence of bosses in rapid succession, testing their strategies and builds. Success in Boss Rush rewards players with permanent bonuses, enhancing their progression.

All Objectives in IDLE BOSS RUSH

In IDLE BOSS RUSH, objectives are structured around defeating bosses, unlocking achievements, and optimizing your kingdom’s progression. Here’s a breakdown of the primary objectives:

Boss Defeat Milestones

Each boss in the game has three achievement tiers:

• Conqueror: Defeat the boss once.
• Hunter: Defeat the boss 100 times.
• Slayer: Defeat the boss 1,000 times.

For example, defeating the Wormhole Worm once unlocks the “Wormhole Worm Conqueror” achievement. Repeating this 100 and 1,000 times unlocks the “Hunter” and “Slayer” achievements, respectively. This pattern applies to all bosses in the game.

Skill Tree and Advisor Objectives

Progressing through the skill tree and recruiting advisors are essential for enhancing your kingdom’s capabilities. Key objectives include:

• Recruiting Advisors: Gain bonuses by recruiting three of the same advisor type in a row.
• Skill Tree Milestones: Unlock and upgrade nodes to improve various aspects of gameplay.

Strategic resets can help achieve these objectives efficiently.

Prestige Objectives

Prestige allows you to reset your progress in exchange for divine gems and permanent upgrades. Objectives related to prestige include:

• Soft Prestige: Requires divine gems and a secondary material like rat tails, wax, or crystals.
• Hard Prestige: Requires only divine gems and completely resets your build.

Prestige is crucial for long-term progression and unlocking higher-tier upgrades.
