En-Gen is a game where players (the Roarkers) spin coloured blocks to generate Monstrowatts (pun of watts).
When four or more blocks of the same colour are connected, points are gained and the Power Meter rises. The game ends when the Power Meter is fully depleted. The "presenter"/ chief engineer/ main figurehead thereof is Dizzee Bolt.

EN-GEN provides Monstro City with all of its energy, pumping out Monstrowatts day and night. Give Dizzee Bolt a hand producing some power and you can earn yourself Rox at the same time.
There are three difficulty modes to choose from: easy, medium or hard. Easy will supply the heaviest amount of time, with medium trailing it behind; hard mode, however, offers the least amount of time. There are 64 blocks in total. Clicking on spinners (circular pin-like things which appear at the centre of the group of blocks) rotate the blocks at an angle; matching 4 blocks will add to the player's Monstrowatts, the substitute for points during the game. The player is given a meter (which is fittingly known as the "power tank") which displays the player's time; as the player progresses—getting to higher levels—the less time they are given. Combos also heavily boost the player's Monstrowatts - after matching a set of blocks, the player's time will elevate.
