How to Win the Last Level in Bubble Bobble

You may have had no problem getting through the first 99 levels of "Bubble Bobble" for the arcade or NES, but the final level, level 100, holds a surprise: The game's only boss fight. Twin dragons Bub and Bob go head-to-head against Super Drunk, called Grumple Grommit in US version of the NES game, to save their girlfriends. Careful use of the Lightning Potions scattered across the room will let you turn Super Drunk into super dust.

Jump up on the platforms directly above where you start to grab the lightning potion as soon as you gain control of your character. On the NES version of the game, you'll have a few seconds where Super Drunk awakens but doesn't move, giving you a chance to climb without dodging his attacks.

Jump down to the ground level and position your character next to the closest wall. If playing a single player game, you'll position your character next to the wall on the left side of the screen. By the time you reach the potion, Super Drunk starts moving in a pattern, bouncing from wall to wall. Run under him to avoid damage, then return to the wall.

Create a tower of bubbles against the wall and pop them when Super Drunk is on the other side of the screen. Popping the bubbles causes lightning to fire across the screen, hitting the boss for damage.

Dodge the bullets that Super Drunk shoots out -- these bullets fly in an arc pattern across the screen. You can jump to avoid bullets or just run under them, but make sure to stick to the left side of the screen; the fight will go quicker if you attack on one side.

Continue attacking until Super Drunk finally succumbs to the damage: Super Drunk has no life meter, so it's not possible to gauge how close he is to death. After you've dealt enough damage to Super Drunk, he becomes trapped in a bubble.

Touch the bubble that traps Super Drunk to end the fight. It doesn't matter where you touch it; any location will pop the bubble.
