Evaluation
B100X launched on January 26, 2021 and has received a steady stream of major content updates ever since. Six major updates have shipped across the game's lifetime: v1.1.0 (March 10, 2021), v1.4.0 "VAULT" (March 2, 2022), v2.0.0 "New Chapter" (March 31, 2023), v2.1.0 "Twilight" (August 30, 2023), v2.2.0 "Turbulence" (July 31, 2024), v2.3.0 "Tranquil" (December 10, 2025), and most recently v3.0.0 "Miasma" (May 27, 2026). This establishes a clear and sustained pattern of major releases roughly every 6–18 months. The developer also milestones the game's seasons (DAWN, QUEST, WONDER, Setting Sun, Twilight, Turbulence, Tranquil, Miasma), suggesting a continuing seasonal content structure. The most recent major update, v3.0.0, added a new season, Main Story Chapter 3, two new jobs, and new features — and was followed by two bug fix patches on June 3 and June 9, 2026, confirming the developer is actively maintaining the game. No future content has been explicitly announced, but the developer has consistently delivered new content on a regular cadence and there is no indication that development has concluded.

About this game
What is B100X?
B100X is an "auto dungeon RPG" that you can easily enjoy during your free time.
This game was created with the concept of "making hack-and-slash accessible to everyone."
With "Full Auto Battle" and "Anything Synthesis System", both easy operation and complicated capture are compatible.
There is also an automatic lap function, so you can enjoy it even during matching of competitive games.
Seal the Eternal Cave
In the world before the birth of mankind, the heavens were dominated by God and the earth was dominated by demons.The player becomes a "witness" who assists the apostle "Holly" of God, and challenges the seal of the "Eternal Magic Cave", which is a terrifying monster's nest.
What is a demon? What is God's true purpose? What is the relationship between the Holly Apostles and humans?
How to play
- Create play data.- Choose a dungeon and a target floor and start your adventure!
- The battle is completely automatic.
- Use experience points, junk, and drop items to strengthen Holly!
