Topdeck Duel

Incremental card roguelike

Topdeck Duel is an addictive card roguelike with incremental game elements. Test your luck and tactical thinking in endless runs where every drawn card can turn the tide of battle!

Fight against the AI in card duels, claim your opponent's cards, upgrade your deck, and unlock global perks between runs. Can you beat all 10 levels and become the ultimate champion?

⚔️ SIMPLE RULES, DEEP TACTICS
The core combat is simple: you and your opponent each draw one card. The one with the highest power takes all the played cards! But if the power is tied, a "War" begins: players draw additional cards face down and face up, raising the stakes to the limit.

🧩 SMART DEPLOYMENT
After gathering enough cards, you enter the Deployment phase. This is your chance to turn the game around:
— Place cards in 6 slots to trigger powerful effects.
— Your own cards give you buffs, increasing your deck's power.
— Enemy trophy cards apply debuffs! Place them wisely until you can convert them to your side.
— Use unique mechanics: Reroll unwanted cards, Swap their positions on the board, or use Prediction to peek at the enemy's future moves!

🃏 BUILD THE PERFECT DECK
After every victory against an opponent, you claim some of their cards. On the Merge screen, you can:
— Combine 3 identical cards into one card of a higher rarity (from Common to Legendary).
— Spend Influence to recolor an enemy card into your own, turning its debuffs into powerful bonuses.
— Burn excess cards to gain valuable resources.

📈 INCREMENTAL PROGRESSION
Lost? No problem! Every attempt makes you stronger. Earned gold is kept after a defeat. Spend it on global upgrades to prepare for a new run:
— Gain "Royal Insight" or "Tactical Exchange" for a combat advantage.
— Increase your starting Influence with "Noble Pedigree".
— Unlock advanced card alchemy features through "Equal Trade" and other unique upgrades.

With each new run, you'll progress further and further. Start small, adapt your strategy, hoard gold, and become a master of Topdeck Duel!
