This guide will teach you the basics of the game.

Destroying Blocks

Almost everything can be destroyed by tapping on it.
Tap some trees and start gathering wood, useful to craft basic items.

Gathering Resources

Blocks drop useful resources, needed by many craft recipes.
In the world you will find crates and chests. They can contain treasures, weapons, and much more!


Moving Around

Moving your character is easy. Just slide your finger in the direction you want to move.


When you are near the edge of a block you can do a dash jump by swiping diagonally, up or down.

Breaking Blocks

Tap blocks repeatedly to break them
Enable the 'hold to break' option in the main menu to break blocks by holding your finger on them.

Climbing Ladders

To climb ladders, just swipe up or down.
You can dash jump from ladder edges.


Swimming is allowed in blocks full of liquid.
To swim, swipe in the desired direction.
Keep breath under control and remember that some liquid hurt you!



The inventory contains your backpack, the crafting table - addons, and the equip panel.


For a more detailed explanation see the Craftbook page. The craftbook contains all available crafts and the guide.
If simple crafting is enabled the craftbook is also used to craft items.


The map shows an overview of the world.
You can zoom the map further back by holding your finger on the screen when it is opened.


You have some slots to the right of the screen.
These are called 'quickslots' and are used to hold items and have quick access to them.
Tap a quickslot to select it.


The chat button is only available in multiplayer.
Use it to chat with other people!


Crafting is the ability to create items using more basic ones.

Many recipes require an Addon (such as a workbench) to be crafted. To use an addon you can either stand directly in front of it and open your inventory, or stand adjacent to the addon and tap on it. The background of the crafting area (not visible with Simple Craft enabled) will change, according to which addon you're using.


Crafting recipes can be discovered by consuming Craft Notes. You can view the crafting recipes you have unlocked by tapping the book icon on the lower-left to access the crafting book. Here you can also see how many undiscovered recipes there are left.

If you are playing with Standard crafting, you do not necessarily need to have a recipe unlocked to be able to craft it. As long as you know the recipe (i.e. you looked it up online, or have the recipe memorized), you can craft it regardless of whether you have unlocked it yet. However, if you are playing using Simple Craft, you can only craft items if you have the recipe unlocked.

Craft Notes

Craft notes have a small chance to drop when breaking any block. Breaking Crates is good way to find craft notes as they drop from crates more frequently than other blocks. Tapping and holding on a crafting note in your inventory will consume it, and add the recipe to your crafting book.

Standard Crafting VS Simple Crafting

Junk Jack has two different methods of crafting. Standard crafting is the default, but if you wish you may enable Simple Crafting instead.

Standard Crafting

Standard crafting is the default method of crafting. It is done by arranging items in a specific pattern within the 3x3 interface on the right side of the inventory. Then tap the button to craft one; or hold it to craft many (if you placed enough resources in the grid).

A feature unique to standard crafting is that the 10 slots of the crafting grid in your inventory can be used as additional storage space.

In standard crafting mode, the craft book serves as a guide that stores any recipes you have unlocked. You do not need to have a recipe unlocked to craft it, however.

Simple Crafting

When using simple crafting the crafting grid within the inventory disappears, instead crafting is done directly from the craftbook. Simply gather the required resources into your inventory and stand next to the appropriate addon (if necessary). Now open your craftbook and tap the craft button on the item you wish to craft. You must have the recipe unlocked to be able to craft the item.

Using this method individual items will take some time to be crafted, roughly equivalent to the time it would take a user to arrange the items in the standard crafting grid. This works well for crafting a few items, but when crafting large batches of items it will take longer.

The Craftbook

The Craftbook is a small book icon button the the lower left corner of the screen. This contains all recipes currently in the game (or in your current version) and displays the crafting arrangements for items.
The Craftbook can be completed by purchasing the Full Craftbook iAP for $0.99 USD or by finding all possible Craftnotes by breaking blocks along in your adventure(s). The full Craftbook is displayed as the regular Craftbook, but with a gold border to the craftbook icon, instead of the regular silver ot gray border.
Alternatively, if the Craftbook is completed normally, the borders will remian the same, but the craftbook button with have a hammer atop the craftbook icon.


Moving Items

To move an item, just drag it.
If you don't like dragging, enable the 'tap to move' option.

If the item is in a quickslot, you can tap to consume it.
