# 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! - Aim for the deepest part of the "Eternal Cave". # Link There is also a PC/iOS version. * Official site https://b100x.nussygame.com/ * Change log https://b100x-history.tumblr.com/ * User support https://nussygame.zendesk.com/hc/

Verdict
The clearest difference is in-app purchases: デビルハーモニクス at none against B100X's 10. デビルハーモニクス also leads on update cadence (every 2 days vs every 10 days) and iOS requirement (11.0 vs 15.0). B100X's advantage is ratings volume (220 vs 4) and review sentiment (84% vs 70%). On price, rating, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. B100X sells 10 in-app purchases, starting at $2.99 per month. デビルハーモニクス asks for nothing beyond the download.
デビルハーモニクス holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: B100X has 220 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 84% of B100X's written reviews are positive against 70% of デビルハーモニクス's, so the app with the better star average is not the one people write more warmly about.
B100X ships an update every 10 days, デビルハーモニクス every 2 days. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
