We hope you enjoy the new features and fixes to Island Bound and other legacy issues, and we’ll continue as always to monitor your feedback and suggestions.

The Bucket 1.01 (25 May 2020)

Cleared for Transfer & Bucket Update (14 May 2020)

To all wardens,

Today we celebrate the release of Cleared for Transfer and The Bucket update, introducing several new exciting mechanics, wall types, objects and much more to your game. Check out the patch notes below!

Cleared for Transfer:

With Cleared for Transfer, we introduce the idea that prisoners can now transfer between security sectors of your prison - you control the criteria or rules for prisoners to transfer. In order to create a ‘motivation’ for prisoners to transfer, you can also link and/or restrict privileges to individual security sectors. You can increase (or decrease) a security sector’s grade (e.g. Min Sec), by attaching privileges (such as Visitation), adding new objects, equipment, and facilities, and making regime changes (such as more Yard time).

Ultimately your aim should be to entice prisoners to want to transfer into a more comfortable or privileged sector, and then encourage them to change their ways in order to meet the criteria for transfer.

Elements that are tied to the Prisoner Transfers system:
The Prisoner Transfers system can be enabled and disabled in the map settings. ​

Staff Needs

Your security staff now have needs, in much the same way as prisoners. This is optional, and can be enabled when creating a new prison, or enabled from Extras -> Map Settings.

You must take care of your staff needs, or else your staff will begin to perform their duties badly.

The staff members affected in this update are:

If staff are happy, this contributes in a positive way towards the temperature of your prison. Likewise if they are unhappy, this will make the prison "hotter" and lead to more trouble later.

If you do not take care of your staff they will become "pissed off", and begin to perform their jobs badly:
Staff break times

Update 6c (02nd May 2016)

In addition, seasons and seasonal variation in temperature is now disabled unless you have "Weather" enabled for your prison.

We are aware of some bugs remaining in the temperature system, which we will address. However we felt the exposure death bug required an immediate fix.

Update 6b (29th April 2016)

Seasons and Weather
Map Settings

You can now adjust the settings of your prison from a new screen called "Map Settings", found in the Extras menu.
This screen lets you enable certain options that may not have been enabled (or even available) when you first created the map.
Nb. You can enable these options, but you cannot disable them once enabled.
Available options:

Job Prioritisation
Performance Work (continued)

Further performance gains were made this month through several different approaches to optimisation.

Bug Fixes

Temperature and lightmap system corruption bug fixed.

Update 5c (11th April 2016)

"Having read the feedback, we think that we made the hot water pipes too fiddly for many players by requiring every shower head to be wired up to warm water to avert a riot of frigid prisoners.

We've now changed the system so that a hot shower is an optional luxury and gives a benefit to prisoners' well-being if you feel generous enough to provide it."


Update 5b (24th March 2016)

Performance optimisations

We focused on performance this month, and achieved a speed boost of at least 50%.
This work is ongoing.

Thermodynamics (continued)
3d mode has been discovered

Update 4b (04th March 2016)


The game now models the ambient temperature of the world, and it's effect on your prisoners.
The outdoor temperature will vary during the day, and turn cold at night
The temperature of your indoor areas will be affected by this. Indoor areas near doors and windows will lose heat fast.
Certain existing objects generate lots of heat : Cookers (when in use), power stations, water pumps

Quick Build menu
New prison sharing options

Update 3d (05th February 2016)

Guard Towers + Snipers

You can now build guard towers around your prison for an extra level of security, intimidation, and force.

New entity type : Snipers

Hired from the staff menu.
These guys will equip themselves with a scoped sniper rifle from the armoury, if you have one.
They will then take turns manning the guard towers you have built.
Snipers will project 'Suppression' to all prisoners within their line of sight.

Secure Visitation Booths

You can now build secure visitation booths in your visitation room if you choose, instead of the usual tables.
A secure visitation booth has a glass panel that seperates the inmate from the family member, and they use a phone to talk.

Female Names-in-the-game

If you are a Name in the Game customer, you can now update your bio and create a female prisoner if you wish.
Go to to do this.
