The Tower of Druaga/Walkthrough
 Original (arcade) version
While the layout of the floors, and the enemies they contain, change from level to level, the basic goal of The Tower of Druaga is the same throughout. You must navigate the maze in search of the . Once you find the , you are free to locate the and escape to the next floor. Once you ascend to the next floor, you can never return to the previous floor. In higher floors, special items may be required in order to see the location of the and the .
Every floor (with just a few exceptions) contains a hidden . The way reveal the changes with each floor. Some methods are intuitive, while other methods may seem bizarre. For the most part, you not only want to find these treasures, you will also need them in order to succeed. The treasure found on each floor, as well as the method to obtain it, stays the same for that floor every time you play.
The maps shown in this walkthrough are for the arcade and any arcade based variant (such as in Namco Museum Vol. 3). The PC-Engine, Famicom and Game Boy versions contain different floor layouts than the arcade, and thus the mazes here do not reflect those found in either version. The treasure reveal methods for the Famicom are the same as the arcade where positions on the map are unimportant. Many of the treasure reveal methods for the Game Boy are similar, but there are a few that have changed entirely. Where ever possible, the walkthrough will attempt to describe those differences. As a bonus to Famicom, Game Boy, and PlayStation players, experts who complete the game successfully are awarded with a special code that will unlock a more difficult version of the game known as Another Tower. In this tower, the monsters are tougher, and the treasure reveal methods require far more patience and skill. The Famicom and Game Boy solutions for Another Tower are similar, but the PlayStation version has it's own set of mazes, monster groups, and solutions. The special codes are revealed below:

 PlayStation's Darkness Tower
In addition to the Another Tower found in the Namco Museum Vol. 3 version of The Tower of Druaga, there is a second secret set of 60 floors (this time numbered from 61 to 120), referred to as the Darkness Tower. On these floors, the treasures are in a different order, and the gameplay is even more difficult. The solutions to those floors are on the following page:
 PC-Engine (TurboGrafx-16) version
The PC-Engine version of the game, while very faithful to the original in terms of game mechanics and controls, it very different in it's presentation, and treasure sets. The game can be played on one of three difficulty levels: Easy, Normal, and Hard. A fourth difficulty, Professional, is reserved as the Another Tower version of the game, and does not require a code to access. Both the regular and professional solutions can be found on the following page:
