The first type is the game for speed. During 60 seconds you are to destroy a maximum number of cockroaches.

The second type is the game for total elimination. You have to destroy all cockroaches. The number of cockroaches doubles every 6 seconds.

To fight the cockroaches you can use the following weapons:

Anti-cockroach spray, which is a strong toxic weapon. It kills a cockroach within the effective radius and other cockroaches that would appear in the ring within three seconds after the application. No charge limitation, but you cannot use is 5 times in a row or 10 times during any 20 seconds. Otherwise, you will be unable to continue your battle.

The scattergun is good for long-distance attacks. Still you have to spend extra time recharging it and have limited resources of shots. Your ammunition amounts to 100 cartridges.

Mini Gun. You can fire 30 cartridges per 10 seconds and is equipped with 5 magazines. Like with the scattergun you need to spend some time on recharging.

Machine Gun. It can fire 300 cartridges per 60 seconds and has 3 magazines. You also need some time to recharge it.

All weapons except for the first one are destructive for the items located in the room. You will be losing points for any damage made.

If you fail to destroy the cockroaches, they will eagerly migrate to other rooms of your house and even invite other insects to become their guests.
