Egg Mania

If the player tries to take a short cut and not build complete floors, the structure will start crumbling and the water will come up faster.

There are plenty of obstacles, both from the game and from competing opponents.

Falling meteors can knock the player down into the water, while bombs thrown by the opponent will destroy parts of the player's structure.

The main modes include Over Easy and Hard Boiled, the difference being that in the latter a different difficulty can be chosen.

There are four extra modes: Survival, Solo, Time Trial, and Bomb.

In Survival the player must survive as many rounds as possible, while the goal in Solo is to increase the overall score by completing rows and performing combos; Time Trial challenges the player to continually beat his or her own best time; finally, in Bomb, whoever destroys the opponent's tower first wins.

Compared to the GBA version, the console versions have improved graphics and sound, cutscenes at the beginning of each level, a play area that is wider by one block, two additional modes (8-player Tournament and Custom, where the rules can be customized by activating different options), but lacks the Time Trial mode.

Otherwise, they are completely identical, both in gameplay and level design.

Egg Mania for Nintendo GameCube is currently worth €21.87 loose, €18.35 complete in box, and €35.06 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Egg Mania has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Egg Mania, loose is €21.87 and CIB is €18.35 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
