Tower of the Ancients

Tower of the Ancients is a falling block puzzle game where the player builds a hollow tower. Stones with different symbols on them come in from the top and the player has to place them on the circular game field. When three stones with the same symbol are placed to each other - horizontal, vertical or diagonal - the vanish and give a point each. When the tower reaches the top of the screen the player loses.

The game features ten levels with basically one winning condition: earning enough points. But the higher levels also introduce restrictions, e.g. only horizontal or vertical rows count.
