Navigation and the address bar

On the public website, the address bar stays at cavecrafter.com as you move between planner screens. Use the app menu or your browser’s Back and Forward buttons to revisit screens. Reloading the same tab can reopen the screen you were viewing.

Temporary choices, such as Profit Loss filters and the purchases or gifts selected in Production Line, are cleared when the app reloads. Restoring a screen does not restore those choices; your saved calculation preferences still apply.

Existing links to specific planner screens remain valid: they open their destination, then the address returns to the site root. Copying the address bar shares the website, not the current screen or scenario. Guides, Privacy and Terms of Use keep their own page addresses.

Start with the question you want to answer

Your first plan in four steps

1. Check your parameters. In My Factories, enter the levels and Mastery you own; you can open it from the panel beside the mine/factory selector in Factories. Review the power price and daily hours in Settings. Configure the two speed boosts in Bonus Speed; the Change button beside the header boost opens that section.
2. Compare against the market. Use Prices to check the values being considered and Profit Loss to compare purchase modes.
3. Investigate a chain. Open Production Line to understand where costs come from and the effect of buying an intermediate resource.
4. Build a batch. In Simulation, select your factories and the cycles for final products. Check the summary to see what will be sold and what still needs to be bought.

In Factories, the first card shows the total resources required to reach the maximum level of the selected mine or factory, grouped by resource with icons and quantities. It adds all Upgrade to level requirements, including construction at level 1. This is the full total, independent of the level saved in My Factories; production inputs are not included. The total cost in COIN uses the current buy prices, including fees, and updates when prices change. It is shown as unavailable if any required price is missing or invalid, rather than displaying an incomplete total.

The planner uses a uniform page background and dark gray panels. Selected choices use a gradient. Login, Donate, theme and language controls keep their own appearance. Hover over or tap the information icons to read explanations in a compact box with wrapped text.

The header displays both 1 COIN = X USD and 1 USD = X COIN. The second value is the reciprocal of the same available exchange rate; both update together.

Questions before you start

MasterPiece: league requirements and estimated costs

Open MasterPiece to consult the leagues, resources, milestones and dates of the event. The Target milestone tab shows requirements and estimated purchase costs; the initial milestone is 100%, and other milestones or full resource targets can also be selected. The Simulation tab estimates Power for a resource and quantity you choose. Without an account lookup, the page does not assign contributions or progress to you.

You can enter your CraftWorld Account ID / Voya ID to look up the associated league. After a successful lookup while signed in to CaveCrafter, the ID is saved with your account preferences. In Settings, you can change or remove the saved ID without starting a lookup. When you open MasterPiece with a saved ID, it is restored and queried automatically; you can also use the lookup or refresh buttons. The lookup uses CaveCrafter's server and does not require your game password, wallet signature or private key. See the Privacy Policy.

After an account lookup, progress, recorded contributions and unlocked milestones are displayed as reported by the source. Even after an account lookup, these values may be shared references and are not independently verified as your personal progress. Check them in the game before planning a contribution. A percentage can exceed 100%; the resource target may refer to a later milestone, and the displayed percentage is not recalculated from the points ratio.

The remaining quantity is the cumulative requirement of the selected milestone minus the cumulative contribution reported by the source, with a minimum of zero. Without an account lookup, the estimate uses the full requirement of that milestone. The estimated COIN cost multiplies that quantity by CaveCrafter's current buy price, with fees already included. Fees are not added again. The estimate updates when prices change; a missing or invalid price must not be interpreted as a free resource or a complete total.

In Simulation, select a resource required by the league and enter a quantity greater than zero. Power to donate applies the league's cumulative cost brackets from the first daily bracket. The official wiki confirms that costs rise with donations of the same resource during the day and reset at 00:00 UTC. Today's donations are not known, so the estimate does not calculate their additional cost. Check the actual amount in the game. Missing or invalid brackets make the result unavailable.

Power to produce uses the complete production chain and the same factory levels, Mastery and whole-cycle setting as Production line, including the Earth mine when needed. Change this global profile in Production line or Settings. Saved purchases, gifts and interrupted branches are not applied. Total Power adds production and donation; it is unavailable if either estimate is missing.

Crown estimates use the resource rate configured for this event and league. Enter Previously accumulated crowns manually; the default is zero. Shared points returned by the source are never used as your personal balance. Estimated crowns are added to this amount to find the highest unlocked chest threshold.

The simulation starts with a global percentage of 100%. Rewards use the highest configured milestone at or below your selected percentage, without interpolation or adding different global stages. The totals accumulate unlocked chest levels, including any you may already have claimed; previous claims are not deducted. FREE and extra RawrPass rewards are shown separately, and the pass total adds both. Rank Reward is excluded.

Crown rates, chest thresholds and EARTH/WATER/FIRE/COIN rewards are maintained in the Admin for each event and league. An incomplete reward cell makes the corresponding total unavailable; a recorded zero is valid. Missing chest thresholds or rewards are not invented and must be entered before those estimates are available. The simulator does not donate resources, buy a pass or claim rewards.

The source can be delayed or temporarily unavailable. The page indicates the data timestamp; a fresh market price does not mean the MasterPiece data was refreshed at the same time. For visitors who are not signed in, the ID stays only in memory while this app tab remains loaded. Results and stage selections also stay in memory. Clearing the MasterPiece lookup removes the displayed ID and result, but does not delete an ID saved with your account; use Settings → Remove to do that. Signing out clears the account-specific information from this visit; the saved ID remains available after you sign in again. The ID is not saved in shared browser local storage, URLs or application diagnostic logs. Looking up a league or calculating a cost does not donate tokens or perform any action in the game.
