Sky Kingdoms is a marble shooter game with a fantasy theme, where the
player controls a winged device moving sideways at the bottom of the screen,
shooting spheres towards a moving string of multicolored balls to make matches
of three or more of the same type, making them disappear. The line of spheres
rolls on a twisting track that occupy most of the screen state, going slowly
towards an exit hole at the end of the course. If three or more balls enter
the exit, the game is over, the player loses a life and has to restart the
level. The objective is to make enough matches to fill a meter at the bottom.
Coins and jewels fall after some of the matches, and can be collected with the
device.

Power-ups appear randomly on the tracks, inside glowing spheres that have to
be matched to release them. After showing up on the line, they keep flowing
with it until being activated with a ball hit. The blue power freezes the
nearby spheres with a coat of ice, making them breakable. The red fiery power
destroy adjacent balls in a huge explosion. The white power with an X symbol
gives an aiming laser to the shooting device, to improve accuracy. The smoky
color bomb paints the balls with its own color. The purple power breaks random
spheres with lightning bolts. The green arrow makes the ball line move
backwards for a few seconds. The yellow S temporarily stops the spheres. The
color remover destroys several balls of its color. They can be upgraded on a
separate screen between stages, where the player can buy improvements for each
power-up with the coins netted while playing the level.

There are three slots at the bottom interface for special power-ups, received
after playing well and making lots of points in a short period of time. They
can be clicked to be deployed directly. The multicolor ball can be used as a
joker sphere, matching any color. The meteor breaks the first ten balls of the
line. The golden cube can be placed on the track to temporarily block the
passage of the line.

Some special levels have slight variations of gameplay. In the combo stages,
the objective is to make a series of successive matches, using the spheres in
a more strategic manner. In the snake stages, the player has to make matches
while avoiding the collision of occasional flying objects with the shooting
device.
