1. Start by tapping the "Play" button on the main screen to enter a match against an opponent.

2. You begin with a hand of five cards, each showing a number for attack power and a symbol for a special ability.

3. Look at the top of the screen to see your health bar and your opponent's health bar; the goal is to reduce theirs to zero.

4. Tap any card in your hand to select it, then tap an empty slot on your side of the board to play that card.

5. Each turn you get a limited amount of energy, shown by glowing pips at the bottom; stronger cards cost more energy to play.

6. After placing cards, tap the "End Turn" button to let your cards attack the opponent's front row or directly hit their health.

7. Watch for cards with shields or healing icons; tap them first to block damage or restore your health before attacking.

8. If your opponent plays a card with a lightning symbol, tap a card with a shield symbol to counter its special effect.

9. Between rounds, you see a shop screen; tap the coin icon to upgrade your starting coins, or tap the fist icon to boost your strength.

10. Use coins you earn from winning matches to buy stronger cards from the shop before starting a new battle.

11. If your hand is full of weak cards, tap the red discard button to throw one away and draw a new card from your deck.

12. Keep tapping and dragging cards quickly, because each turn has a timer; if it runs out, you skip your attack phase.
