Power Up Chess

Chess variant where every 4 turns a power up appears on the board. Power Ups can be colected by having a piece land on it and can have various effects, but most of them pass after an amount of turns.

You can see what a power up does by hovering the mouse above it for one second.
The Power Ups are:

- Frozen King, the oponent King wont be able to move. Lasts for 4 turns.

- Regular Shield, if the piece that has the shield is captured, instead of being captured the shield breaks. Lasts for 4 turns.

- Small Promotion, if a pawn colects this power up he will be able to promote to a bishop, rook or knight. Instant.

- Angel Wings, the piece that has wings can move to anywhere that it could go if the board was empty. Lasts for 2 turns.

- Caboom Bomb, if the piece that has the bomb is captured, the capturer also is captured. If the power up ends, the piece with the bomb is captured. Lasts for 8 turns.

At the moment you can only play the "pass to play" mode, where both players share the same device.
