HECK: Know Your Weaknesses is an adventure rage game set in Heck, a fictional underworld setting not unsimilar to Hell. There are some ground rules for playing HECK: Know Your Weaknesses, which you may want to keep in mind so the "minimal" amount of rage is forced upon you during your gameplay.

1. Disable your popup blocker.
2. Do not stop HECK: Know Your Weaknesses from opening alert windows. (This option will pop up in browsers like Chrome after HECK: Know Your Weaknesses has opened a certain number of alerts, please do not check it.)
3. Do not input any answers to an alert window other than ones you are asked to input. Doing so will result in... consequences.
4. Know your weaknesses.

Now you may be able to play HECK: Know Your Weaknesses. Remember, most interaction is done through alert windows like this. You may be asked to complete a math problem, answer a question, or any number of things.
