How to use the Mysterious Island tool

This tool shows the latest Mysterious Island layout and lets you plan your path to maximize rewards while minimizing resources.

Rewards and emerald values are based on HWG and rarity fair.

Best Paths (October, 2025)

Sorted by Emeralds per Move (highest first).
Note: Compared to September and Cascade islands, this island seems to be more expensive.
I would recommend to skip this map.

Methodology & Assumptions

Data sources. Values use the same pricing sheet as our other pages. Screenshots are simulator runs on the October layout.

How we score. For each path we total the emerald-equivalent of all rewards, then compute Emeralds per Move (EPM) = Total Emerald Value ÷ Explorer’s Moves. We rank by EPM for efficiency and also show total emeralds for volume-focused players.

Interpreting the rankings. Overall, this map seems to be very expensive. However, if you decided to spend moves on this map, #1-#5 are the efficiency leaders with very strong Chest of Patterns counts; #1 and #4 also include Absolute Artifact Chests ×100. If you’re move-constrained, pick #5, #8, or #10; if you want raw totals, pick #1, then #4 or #2.
