About the challenge run generator

Beaten the Elite Four a dozen times and looking for a reason to replay? Challenge runs add self-imposed restrictions that turn familiar games into genuinely difficult experiences. This generator picks from 35 rules across 5 categories to build a custom ruleset every time.

Rule categories

  • Team: restrictions on which Pokémon you can use (monotype, NFE only, BST caps, solo runs)
  • Battle: combat limitations like Set mode, no items, level caps, and permadeath
  • Catching: encounter rules such as one catch per route (Nuzlocke style) or Poke Balls only
  • Economy: resource limits like no Poke Mart shopping, no TMs, or no Pokémon Center healing

Presets and difficulty scaling

Four built-in presets cover the most popular formats: Nuzlocke (permadeath plus one catch per route), Hardcore Nuzlocke (adds level caps and no items), Solo Run, and Poverty Run. Each rule carries a 1 to 5 difficulty rating, and the generator spreads picks across categories so your ruleset is varied rather than stacking five team restrictions.

Sharing a run

Set the difficulty cap lower for a manageable first challenge, or leave it at 5 for a punishing run. Every roll gets a seed, so share run copies a link that reproduces the exact same ruleset for anyone who opens it. The combined difficulty score tells you how brutal your generated ruleset will be.
