Rainbow Tower Defence

Building towers is only the beginning. In this innovative tower defense, you must draw powerful 'Lines' between your towers to halt the enemy advance! Strategically deploy towers of the right colors and combine functional lines to create an impenetrable defense against the approaching monster hordes

They targeted only our vital infrastructure—power lines, building supports, and major bridges—dismantling the civilized world in an instant. Just as humanity fell into total despair, Dr. Strings made a breakthrough discovery.These invaders are mindless entities that perceive nothing but color. They possess a singular, primal instinct: to swarm toward 'Lines' like moths to a flame. Now, humanity begins its counterattack, centered around the elite 'Liners.'<h2 class="bb_tag" >[Game Overview]</h2>Don't just build towers. The 'Lines' you draw between them are your most powerful weapons.
