krank is a little casual game objective of which is to is to remove all anchors and magnets.
A magnet will vanish if it captured at least as many balls as circles are rotating around it, or if all the captured balls have the same color as the magnet, or if it stayed for 3 seconds in the above condition. If a magnet is fully loaded, but includes links or balls of a different color, it will explode, but not vanish.
Anchor will vanish if it is connected to as many other anchors as circles are rotating around it, if all the connected anchors and links have the same color as the anchor, if all other anchors of the same color are fully connected, or if all the above conditions are valid for 3 seconds, those anchors will be removed. If an anchor is connected to another anchor, but the connecting chain includes links of a different color, it will explode, but not vanish.
