To hack a terminal, clear the firewalls and rotate the board to allow your avatar to enter the SYSTEM-CORE. Watch out for defence programs called subroutines that will attack your avatar.
There are a variety of subroutines that will attempt to prevent you from reaching the SYSTEM-CORE. They will attack your avatar, other subroutines, bombs, and SYSTEM-CORES with attack-locks.
Blocks which turn into new subroutines will appear on the board after each turn in which you clear a firewall of less than 4 blocks, and each turn while the Alarm is active.
Large clears can spawn bonuses, Which provide advantages when your avatar drops down on them from above.
In higher levels, the SYSTEM-CORE is protected by one or more locks, which must be unlocked in order.
Moving the cursor over a tile will give you useful information about it, depending on what it is:
- Hovering over a firewall (coloured block) will light up the group of blocks that will be cleared if you click on it. The cursor will also change shape to indicate whether clearing this group will cause new subroutines or bonuses to appear.
- Hovering over a subroutine or bomb will light up its attack range.
The following gadget modifications are related to Hack or directly provide bonuses during Hack.

The Basics of Hacking Terminals
"To hack a terminal, clear firewalls and rotate the board to allow your avatar to enter the SYSTEM-CORE. Watch out for defence programs called SUBROUTINES that will attack your avatar."
Turn Subroutine Defences to Your Advantage
"SUBROUTINES follow set rules of engagement -- learn their rules and you can turn them to your advantage. New Subroutines are spawned whenever you make clears of less than four firewall blocks."
System Core may be Locked
"Some terminals will have stronger anti-hack measures such as a LOCKED System-Core. To unlock the core you must touch the KEY to the locked System-Core."
Bonuses and Alerting the System
"Larger clears might spawn a BONUS which you can pick up with your avatar to gain their effects. CURSOR ICONS warn you when a small clear will alert the system and spawn Subroutines."
System Core can be Locked in Various Ways
"On harder Terminals the System-Core is LOCKED in multiple ways. You must unlock them all before your avatar can enter the core."
Know your Enemies
"Knowing each of the SUBROUTINES’ rules of engagement is the key to planning your strategy while hacking. Remember, Subroutines will attack ANYTHING that comes into their range."
