Pulse Defense is a luck-based merge tower defense game with a twist: your units are also poker cards. Draw random units, merge matching pairs to level them up, and line up poker hands — Pair, Straight, Full House, Five of a Kind — to supercharge an entire row. Hold your lane against endless waves while sending mobs at an AI rival in a 1v1 duel. Every run is a fresh roll of the dice, but placement and timing decide who survives.

■ MADE FOR YOU IF…
• You love random defense and merge TD games where the next draw can change everything
• You want quick, one-handed strategy rounds, not a 40-minute campaign
• You love building combos — scoring a poker hand here feels as good as in any roguelike card game
• You want an offline single-player game with no account and no pay-to-win

■ HOW TO PLAY
1. DRAW — Spend gold to summon a random unit from five rarities: Common, Rare, Epic, Legend and Primordial (a 1% drop).
2. MERGE — Combine two units of the same rarity and level to level up, all the way to Lv.6.
3. BUILD HANDS — Each build row holds 5 units. Level is the rank, rarity is the suit. Complete a poker hand and the whole row gets stronger.
4. DEFEND — Units fire automatically as waves climb and mobs toughen. Before each boss the clock stops for an 8-second prep window to re-plan your board.
5. SEND MOBS — Spend gold to push mobs onto your rival's lane. Break their base first to win, then keep going in Survival mode to pile up score.

■ POKER HANDS — STRATEGY ONLY THIS TD HAS
One row = one hand. Duplicates count once, so merging is always the smart move.
• Pair, Two Pair, Three of a Kind, Full House, Four of a Kind, Straight, Straight Flush, Five of a Kind
• Higher hands scale row damage up to ×9 and attack speed up to ×2
• Hands lay lane effects — spark, mud and fire zones that slow and burn every mob passing by
• Four of a Kind and above unlock execution volleys with bonus boss damage
Where you place each unit matters as much as what you draw. Same luck, different results.

■ LV.6 SPECIAL SKILLS & BASE STRIKE
Max-level units unlock a rarity-specific ultimate:
• Rail Lightning — a bolt races down the rail, zapping everything on it
• Tidal Wave — a wave rolls along the path, hitting and slowing all
• Map Meteor — a heavy hit on every living enemy
• Push Back — a shockwave knocks every mob back to the start
• Freeze Wipe — freezes the entire map, wipes it, and pays out a gold jackpot
Your base fights too: it charges up and unloads a burst that chains through the front line. Upgrade it with gold for extra shots.

■ GAME MODES
• BOT DUEL — Four difficulties: Easy, Normal, Hard, Extreme. Harder settings multiply your score. Plays fully offline.
• DAILY CHALLENGE — A new seed every midnight; everyone gets the same draws, so it's pure skill. 3 attempts a day, difficulty rotates by weekday, Sunday is Extreme.
• STREAKS — Finish a daily run to keep your streak alive, with milestones at 3, 7, 14, 30 and 100 days. Optional evening reminder when it's about to break.
• GLOBAL LEADERBOARDS — Weekly, monthly and all-time Hall of Fame top 10. No account, just a nickname.
• BRAIN ACTIVATION — Every finished run turns score into XP that evolves your brain avatar from Neuron Seed to Transcendent Mind. A fun progression meter.

■ WHY YOU'LL KEEP PLAYING
• One minute to learn, endless depth: luck gets you started, strategy takes you further
