Defend your king against 8 waves of black attackers.
How to play
You command the white defenders at the bottom of the board. Waves of black attackers appear in the top two rows (white edge) and march on your king; after each of your moves the enemy moves one piece. A new wave arrives as soon as the board is cleared, or after 12 turns if you are too slow. Every cleared wave gives you a reinforcement plus a pawn on your back ranks. On Hard the waves bring more knights and bishops early, with rooks and a queen in the late waves; the next wave is forced after 14 turns. If you have no legal move you lose. There is no check: if a piece captures your king you lose. Clear all 8 waves to win; on the last wave, holding out until the countdown runs out also wins.
