Island Treasure Hunt

Multiplier Map ( • ̀ω•́ )✧
How do I use this map?
- Check the map for the tile you are on
- Change your multiplier to match the tile on the map (go as high as you can if you cannot do 10x)
- Roll
- Repeat
How did we come up with this map?
- Calculated the expected value of each tile based on its points value and probability of getting dice.
- Compute the projected value of each tile by factoring in the expected value of reachable tiles.
- Toggled tiles—starting with those with the highest projected value—to 10x in order to maximize overall PPID.
- Ran 10k simulated event runs on the finalized map to validate our approach.
Did we try other maps?
- We ran simulations on several other proposed maps, but ours outperformed them.
- We also explored "safer" maps with lower variance, but none offered a worthwhile tradeoff in efficiency.

Where are the dice?! (╯°□°)╯︵ ┻━┻
Quests that you can complete without rolling
These quests affects your Points per Initial Dice (PPID) as it adds to your '# of Starting Dice'.
Quests that you complete while rolling
These quests give you free dice from just rolling.
- Roll Dice Quest: 65 dice available with breakpoints ranging from 5 to 600
- Getting Points Quest: 60 dice available with breakpoints ranging from 2000 to 100000
- Rolling Around Board: There are a few tiles on the board that gives free dice when you land on them
Should I roll? ¯\\_(ツ)_/¯
Decide for yourself when you should start rolling based on your own risk tolerance.
You can save dice between events to have a better chance of hitting your points goal.
The table below shows you the chance of reaching that points goal based on how many dice you started with.
Tip: During key rotation, you should at least roll until you get 50+ points. This will assign you the lowest rank of 1001+ which still gives one free Chroma Key.
*Start Dice is the amount of dice you have BEFORE you do any rolling. Go to the 'Where are the dice?!' section to see which quests impact this.
| Start Dice | % Chance of Reaching Points | ||||

Tips for Newbies ◕⩊◕
- Save your dice between events to aim for higher points goals.
- Multipliers are unlocked as you collect more dice. They let you get more rewards from a single roll BUT it will cost you just as many dice (20 dice = 2x, 30 dice = 3x, 50 dice = 5x, 100 dice = 10x).
- Save gems for this event (unless there is a clearly better event announced). This is one of the best events to be spending your dice (Island Pack 3, Mythstone Chests, etc.)
- Once you are past 150k power, we strongly recommend saving resources to maximize number of dice you get from each rotation (Chroma Keys, Wishes, Shovels).

FAQs (º～º)
- What is Points per Dice (PPID)?
PPID is calculated as:
= Total Points / Number of Dice BEFORE Any Rolling
= Total Points / (Start Dice - End Dice)This means it EXCLUDES dice gained from:
- Roll Dice Tasks
- Points Breakpoints
- Collecting dice from tiles on the board
Why is this important?
PPID better captures the benefit of collecting extra dice while rolling—something that Points per Roll (PPR) does not fully reflect.
PPR = Total Points / Total Rolls Done.Take this example:
We all agree that landing on a 2x dice tile is a win!
PPR sees it as a negative, since you are ending up with more rolls, which dilutes the score.
PPID, on the other hand, treats it as a positive—more like a refund. You used a dice but got two back.- Should I buy the Island Pack 3 for 750 gem?
Based on our PPID calculations, spending 750 gems for 5 dice is a good deal.
On average, every 1k points earns you on average 1 key (worth 400 gems), plus you get bonus loot just from rolling around the board.- Why aim for 100k points?
Hitting 100k points strikes the best balance between breakpoint rewards AND ranking rewards.
- Going straight for 100k (while skipping events) instead of aiming for 20k every time gives you ~3 more treasure coins, plus extra treasure coins from better rankings.
- Hitting 100k twice instead of 200k once earns you ~10 more artifact shards, at the cost of only ~2 treasure coins.
Caveat: It might be worth spending a little bit extra dice to get higher rank rewards but that is up to you.
- Is there a particular rotation that is better?
Each event rotation focuses on a single resource for the week. You can use that resource to get more dice AND you can roll dice to earn more of that resource. Each rotation also includes a matching artifact as a reward.
The event rotations are:- Chroma Keys and Goldfinger Artifact
- Wishes and Golden Fleece Artifact
- Shovels and Golden Mask Artifact
We recommend prioritizing getting all three artifacts first to complete the set bonus. Once that is done, shift focus to only the Chroma Key rotation as they are the best resource and Goldfinger is the best artifact.
- What should I buy in the exchange shop?
- Cupid's Bow: Cheap, costs only 2 tickets (was available for free during Valentine's event)
- Cupid's Arrow: Completes the set and works across all modes
- Demon Artifacts: Only used in PVP BUT the mode offers valuable rewards
- Otta/Epic Char Shards: Based on personal preference, but I recommend Otta, as he is only available in this shop
- Rare Char Shards: Just avoid them—they are not worth the investment

- I want to track my run. Is there a tool I can use to do so?
Yes! Here is a Google sheet you can make a copy of and start tracking your run.
Dice Event Tracker
If you want to help out, DM your run to @fierywind on Discord as we are doing a study on people's runs.
If you have any questions, feel free to reach out to @kaithulhu_ on Discord.- I think I came up with a better multiplier map. Is there an easy way for me to test it out?
Yes! You can run the same Python script to simulate the event, where you can test out your new map:
