It all starts with opening some cards. Think of them as treasure chests filled with the firepower you need. Inside, you might find a rapid-fire ballista, a frost-spewing mage tower, or maybe a cannon brimming with explosive surprises. Each one is unique, and with a little luck and some upgrades, they'll become even more formidable!

Now, brace yourself, because here they come... waves of bizarre creatures marching straight towards your castle. Goblins with wicked grins, lumbering trolls, and who knows what else lurks in the shadows. It's time for your turrets to shine! They'll unleash their wrath automatically - bolts whizzing, ice shattering, and cannonballs blasting those invaders to smithereens.

Every victory fills your coffers with gold, and with that gold, you make your castle even stronger. Boost its health, so it can withstand those fierce boss battles. Make those turrets hit harder and faster. Maybe even give them a little extra luck – a critical hit can make all the difference!

The enemy hordes keep growing, and with each level you conquer, the challenge mounts. The first few stages of a level are all about the unrelenting waves, but when you reach that fifth stage... hold on tight! Prepare to face a monstrous boss, a towering behemoth determined to crush your castle to dust. These battles are epic tests of your strategic upgrades and the raw power of your turrets.

Of course, sometimes even the best-laid plans can falter. One slip-up, one overwhelming attack, and you're back at the start of that level, ready to try again. Remember, every battle teaches you something: how the enemies move, their weaknesses, what your castle really needs. Victory is within reach. All it takes is a steady hand, a clever mind, and a castle bristling with firepower.
