PRNG Simulator

Predicts upcoming critical-hit rolls (bonus yields, instant mining recoveries) using the game's real formula — not a statistical guess.

How this works

  1. Every critical hit in Sunflower Land is a deterministic function of your farm ID, a fixed item id, your public activity counter for that resource, and the bonus's name — no hidden server secret.
  2. Load your island to auto-fill the real counter (and see whether you actually own the collectible/wearable/skill for the bonus you pick).
  3. The table below replays the exact same formula the game uses, so it predicts your next rolls for real — not just an average.

Fishing catches are resolved on the server and are not covered by this formula — only crop/mining critical hits are predictable this way.

Selected critical hits

Select one or more critical hits above — several of them can genuinely happen on the same collection, so you can combine them here.

    The farm's current activity count for this resource — loading the island fills this in for real.

    Only needed when several plots/nodes of the same resource are ready at once — each gets base counter + its own offset (0, 1, 2…).

    Chance is compared against a 0–100 roll, so a value like 3.33 means 3.33%, not 33%. Golden Sunflower's ranks are genuinely tiny (≈0.14–0.25%) — that matches the game's own source, not a typo.
