Pirate Festival 2026 - Alchemical Secrets New Mini-game

Alchemical Secrets Guide: How to Solve the Pirate Festival Mini-Game

Alchemical Secrets is a new puzzle event introduced during the 2026 Pirate Festival. Unlike most seasonal activities in Infinity Kingdom, this is a genuine mini-game rather than another wheel or combat challenge. Players must reorganize mixed Primal Stones until every Treasure Chest contains stones of a single colour.

The opening stages are straightforward, but later puzzles introduce hidden stones, frozen chests, fixed chests and optional locked spaces. These mechanics make the event considerably more interesting and require players to plan several moves ahead.

More importantly, the harder stages can be completed without spending an Unlock item on the optional locked chest. Opening it gives you more working space and makes the puzzle easier, but it is a convenience rather than a requirement.

Alchemical Secrets Overview

Alchemical Secrets is available to players with Castle Level 20 or higher. New groups of stages unlock throughout the Pirate Festival, so the entire event cannot be completed immediately.

Entering a stage costs one Magic Stone. Once inside, you can leave and return to your unfinished puzzle without paying another entry cost. However, resetting the board consumes another Magic Stone and does not refund the original entry cost.

Each completed stage awards Pirate Festival rewards, including Magic Fishing Nets that can be used in the Fishing Contest. Cleared stages can also be raided with additional Magic Stones, allowing players to collect rewards without solving the same puzzle again. These event mechanics are also confirmed by the official GTarcade Pirate Festival overview.

How the Puzzle Works

Every Treasure Chest contains a vertical stack of coloured Primal Stones. Only the stone at the top of a stack can be moved.

To make a move:

1. Select the Treasure Chest containing the stone you want to move.
2. Select a valid destination chest.
3. The top stone will move into the new chest.

A Primal Stone can normally be moved into:

• An empty Treasure Chest.
• A Treasure Chest with the same coloured stone on top.

The objective is to fill every available chest with Primal Stones of the same colour. Once every stone has been correctly classified, the stage is cleared.

There does not appear to be a time limit, so there is no reason to rush. The game records the number of steps used, but careful planning is considerably more important than completing the puzzle quickly.

Special Treasure Chests

The later stages introduce several mechanics that change how you should approach the board.

Blind Box Treasure Chests

Some Primal Stones are displayed with a question mark instead of their actual colour. The hidden colour is only revealed after the stone above it has been moved.

You should therefore avoid planning an entire colour stack around an unknown stone. Reveal Blind Box stones while you still have enough empty space to handle an inconvenient result.

Frozen Treasure Chests

Frozen chests are covered in blue ice and cannot initially receive or release Primal Stones.

Every time you complete one full colour classification, one Frozen Treasure Chest is randomly unlocked. Its stones then become available and can be included in the rest of the puzzle.

This creates the main challenge of the harder levels. You must first complete colours using the limited active space, which gradually releases the frozen chests and gives you access to the remaining stones.

Fixed Treasure Chests

Fixed chests are marked by glowing rings. Once a Primal Stone is placed inside one of these chests, it cannot be removed again.

Never use a fixed chest as temporary storage. Only place a stone inside when you are confident that it belongs to the colour you intend to complete there.

Optional Locked Chest

Some stages include an additional empty Treasure Chest that can be opened with the Unlock consumable. This provides another temporary sorting space and can make a difficult board much easier.

However, even the harder stages can be solved without unlocking it. The puzzle simply requires more planning and a careful sequence of completed colours.

How to Unfreeze the Board

Frozen chests are not unlocked by waiting. You release them by completing full single-colour chests elsewhere on the board.

This means that the order in which you complete colours matters. At the start of a difficult stage, look for the colour with the greatest number of exposed stones. That will usually be the easiest first classification and your first opportunity to unlock a frozen chest.

Because the frozen chest is selected randomly, you cannot know exactly which stones will become available next. Your opening moves should therefore leave enough flexibility to work with several possible outcomes.

A good general approach is:

1. Identify the easiest exposed colour to complete.
2. Preserve at least one empty chest as working space.
3. Complete that first colour to release a frozen chest.
4. Inspect the newly available stones before committing to the next colour.
5. Repeat the process until the entire board has been opened.

This is where Alchemical Secrets becomes more strategic than a normal sorting game. You are not only sorting the visible stones. You are creating a sequence that gradually unlocks the rest of the board.

Tools and Consumable Items

Several assistance tools are displayed on the left side of the puzzle. These are available for purchase along with additional attempts in the in-game shop.

Items include:

• Undo: Reverses a previous move.
• Reset: Restarts the stage, but consumes another Magic Stone.
• Clear All: Provides a shortcut for clearing part of the puzzle.
• Unlock: Opens the optional locked Treasure Chest and creates additional working space.

These tools are useful, but they should not be treated as part of the normal solution. Many stages, including the more complicated puzzles, can be cleared with zero items used.

Undo is reasonable when you make one accidental move. Unlock is useful if you are genuinely stuck and do not want to spend more time solving the board. Reset should be the final option because it costs another Magic Stone.

Tips for Solving Harder Stages

Preserve Your Empty Chests

Empty chests are your working space. Filling every available chest too early is the easiest way to trap yourself.

Before making a move, consider whether you will still have somewhere to place the next obstructing stone.

Complete the Most Accessible Colour First

Look for colours that already have several matching stones exposed. Finishing one of these stacks quickly unlocks a frozen chest and expands your available options.

Do Not Use Fixed Chests for Storage

A stone placed in a fixed chest cannot be removed. Treat every move into one as permanent.

If you are not certain which colour should occupy that chest, leave it empty.

Plan Around Hidden Stones

A question-mark stone can reveal a colour that does not fit your current arrangement. Reveal these stones while you still have flexible empty chests rather than leaving every unknown until the end.

Think Several Moves Ahead

Before moving a stone, ask three questions:

1. What stone will this move expose?
2. Where can that newly exposed stone go?
3. Will I still have enough space to continue?

A move can be legal and still be strategically disastrous. The important question is not whether you can make the move, but whether the board remains solvable afterward.

Avoid Buying Space Too Quickly

The optional locked chest is deliberately tempting because additional space makes any sorting puzzle easier. Nevertheless, it is not necessary for completing the stage.

Try solving the puzzle normally before spending an Unlock item. If you enjoy this type of game and are willing to plan ahead, preserving the item is entirely possible.

Magic Stones, Raids and Rewards

Each initial challenge consumes one Magic Stone. Once a stage is cleared, it can be raided for another Magic Stone to collect its repeat reward instantly.

Prioritize progression and completing newly unlocked stages before spending Magic Stones on raids. New stages provide their own first-clear rewards and may unlock additional progression, while raids primarily convert spare Magic Stones into more event resources.

The most immediately useful rewards are the Magic Fishing Nets, since these feed directly into the Pirate Festival Fishing Contest. Completing Alchemical Secrets can therefore help you reach additional fishing milestones without purchasing as many Nets directly.

Conclusion

Alchemical Secrets is one of the more enjoyable seasonal mini-games added to Infinity Kingdom. The basic objective is simple: sort every Primal Stone into a chest containing only one colour. The difficulty comes from hidden stones, permanent fixed chests and frozen chests that only open as other colours are completed.

The most important lesson is that the optional locked chest is not required. It can make difficult stages easier, but patient players can complete them without spending the Unlock currency. Preserve your empty spaces, complete accessible colours first and plan several moves ahead so each newly released frozen chest can be incorporated into the solution.

For players who enjoy puzzles, this is a welcome addition to the Pirate Festival. For everyone else, it remains worth completing because it provides valuable Magic Fishing Nets and other seasonal rewards.
