Ninja Star Simulator

Ninja Star Simulator is a ninja-themed merge simulator by Bear Game, launched in December 2021 and updated continuously through March 2026. With 76.9 million visits, 157K favorites, and a 92.9% approval rating, it is one of the stronger performers in the ninja simulator category. The defining mechanic is active merging - players combine three items of the same tier to produce one item of the next tier rather than collecting passively.

The core loop layers collection, merging, and crafting into a cycle that rewards both active sessions and offline time:

• 💰 Collect coins from the map as the base resource for the entire merge chain
• 💎 Merge three coins of the same tier into a single higher-tier coin, upgrading your inventory value
• ⚔️ Craft merged coins into ninja stars - the equipped power items that determine combat strength
• 🗺️ Unlock new worlds like Egypt, each introducing higher-value coin and star types with greater base power
• 💎 Expand your equipped star slots and stack AFK multiplier passes for substantial passive gains between sessions

The AFK progression systems are central to long-term play. The 3x Faster AFK merge pass and 3x Faster AFK craft pass stack together, giving dedicated pass buyers a combined 4.5x automatic processing rate for offline gains.

New players can claim a significant head-start on their very first session.
