## Description

8 probability paradoxes become cards. Defeat enemies with math—Monty Hall, Birthday Paradox & more. 9 rooms, 5 builds, 4 difficulties, plus online leaderboards.

Labyrinth of Probability is a card-battle roguelike where you experience probability paradoxes firsthand.

8 famous probability paradoxes become cards in your hand. Choose your fate, open doors, and use probability to fight through 9 rooms of enemies.

[8 PROBABILITY PARADOXES]
Monty Hall Problem, Birthday Paradox, Bertrand's Box, Simpson's Paradox, False Positive Problem, Two Envelope Problem, Galileo's Dice, HH vs HT. Textbook puzzles become attack and support cards.

[A ROLL OF FATE]
Roll the dice at the start of each run and choose between two fates. Probability Blessing, Probability Curse, Wind of Bias, Mark of Ordeal, Law of Convergence, Path of Calm — your choice shapes the entire run.

[4 DOOR TYPES]
Choose between two doors each room. Fierce (guaranteed reward), Double Strike (play 2 cards), Healing (counter -1 + HP recovery), Observation (see your roll first).

[ENEMY WEAKNESSES & RESISTANCES]
5 enemy types have category weaknesses and resistances. Exploit conditional probability against Goblins, use trials against Dragons. The final boss has random weaknesses each run, with a hint available from room 8.

[5 BUILDS]
Strategist (self-damage -1 + door penalty halved), Gambler (+3% for low-rate cards), Analyst (success self-damage -2), Paradoxer (+8% events, Lv2 reward cards), Chain Caster (premium, +8% attack after support). Match your playstyle.

[4 DIFFICULTY TIERS]
Normal, Hard, Expert, Master. HP and damage scale with difficulty. Higher tiers mean bigger score bonuses. S through D rank evaluation.

[ONLINE LEADERBOARDS]
Compete for high scores with players worldwide. Rankings by difficulty (Normal, Hard, Expert, Master) and overall, across all-time, daily, weekly, and monthly periods. Just set a nickname to join, and link your Apple ID to carry your records across devices and reinstalls. Unlink anytime.

[STRATEGIC RESULT CHOICES]
After defeating an enemy: get greedy or pass safely? When low on HP in Normal mode, a failed card can also open a once-per-room chance to endure or cut your losses.

[DEEP REPLAYABILITY]
- Score history tracks your adventures
- Random events: healing springs, curse traps, treasure chests, dark merchants
- Card upgrades via auto-merge of duplicates
- Rate fluctuation +/-5% (or +/-10% with Wind of Bias) every room

Master probability. Master the labyrinth.
