About Us

DCOBLOX is the best place to discover and explore any difficulty chart obby at a glance or in depth. We offer a curated list and explorer of both popular and niche Difficulty Chart Obbies (or DCOs) for anyone to find and explore new DCOs to play.

History

DCOBLOX began as a single curated list of popular and underrated Difficulty Chart Obbies (DCOs) around 2021, later evolving to a dedicated Roblox game with quick information. In 2026, we revived DCOBLOX and turned it into a dedicated website; DCOBLOX.com.

The DCOBLOX Tier System

A tier is a measurement of a difficulty chart obby's overall difficulty portrayed in units 0-18 (technically 0-25, but no obby has ever reached above 18 by our standards). We review each DCO listed on our service thoroughly in order to determine its tier. We take as many measures as possible to remove any bias and measure any game's difficulty objectively rather than subjectively. As such, our tier system follows stricter definitions and any tier ranking may be different than the creator's personal opinion or another developer's opinion on its tier.

The DCOBLOX Tier System was specifically designed around Difficulty Chart Obbies. It is important to note that the system (DCOTS) focuses on overall complexity rather than the hardest stage's difficulty. For example, if an entire difficulty is rated at a tier 9 except for one or two stages, we roughly call that difficulty a (mid) tier 9 or a low tier 10. We apply this logic to every stage and every difficulty before we get our overall tier ranking. Sometimes our rankers may refer to something as a 'mid tier 9' or a 'high tier 11', but overall in our final scores we use whole numbers only.

The DCOTS (DCOBLOX Tier System) is officially recognized by the Obby Wiki as a reputable tier authority for Difficulty Chart Obby games.
