As of January 2025, the achievement rate for level B-X has reached 5.3%. While this is a logical leap, if the difficulty of levels is the same as B-X, almost 95% of players will likely never beat it.

However, highly skilled players would like to test their limits. For those players, the community is making jaw-droppingly difficult custom levels.

To accommodate these different approaches and to target specific audiences, we are introducing two play styles: Classic and Tech. Although these are subjective terms, we want to share what classic and tech are.

Classic

Classic levels present classic ADOFAI experiences, featuring unique track shapes and vivid creativity.

Classic levels should follow the grammar of the main game. Players should be able to complete Classic levels using what they've learned in the main game (1~12-X & Xtras).

Classic levels features:

• Non-reactionary gameplay
• Intuitive charts
• Readable VFX, overlaps, and gimmicks

Tech

Tech levels feature gimmicks developed by the community that dramatically escalate the difficulty. These include reaction-based gameplay, multi-tapping (pseudos), and fast streams with high BPMs.

Tech levels require players to have advanced skills and physical abilities. It takes great effort to beat those levels.

If the level features the following, it may be considered a Tech level.

• High BPM streams
  • Especially when the BPM exceeds 500, where the 'strict' judgment doesn't narrow further.
  • Typically, players need to use at least 4+ keys to roll over.

• Zips (Trills)
  • The combination of zigzags and swirls in rapid succession.
    • If the zips are not reaction-based, your level can be considered Classic (like T4-X). However, it is advised to keep this to a minimum unless the song tells itself.

Zips

• Multi-tapping (pseudos) tiles
  • Players must acquaint themselves with how to press two or more keys at the same time.
    • Also, players need to adopt a combination of keys to perform multi-tapping tiles during fast streams within a split second.

• Magic shapes: The community practice uses snails and rabbits to make kaleidoscope-like shapes while players tap out consistent streams.
