Egyptian Challenge is a Columns clone. Like in that classic, columns made
of three jewels fall from the top of the screen and have to be arranged to
make matches of three or more of the same type.

The screen is divided in two fields, each side dedicated to a player. The
adversary can be the computer or another player. These fields have tabs at the
top, where power-ups are stored as hieroglyphics for later use. Power-ups are
collected by making combos, multiple matches at the same time.

The power-ups are collected and used automatically. They are organized in four
groups: attack, defense, attack and defense and one that wins the level. Jewel
rain (4 to 5 jewel match) drops gems in the enemy field. Freeze (6 to 7 match)
locks in ice some of the adversary’s gems for a certain time. Disappear (8
match) removes some jewels from the field. Power stone (10 match) drops rocks
in the enemy field.
