Fight the virus! Its crown is constantly growing, it is necessary to rotate the core and find chains of spikes of the same color and destroy them. Chains can be searched in adjacent cells in all directions.
The longer the destroyed chain, the more points are given, and most importantly, fewer spikes will grow on the next turn. Fully grown spikes are worth much more points for destroying than new ones. If a chain longer than 7 cells is destroyed, then the spikes for the next move will not grow at all.
Each step limited in time, take your time until the virus has collected the entire crown.
