Algorithm Heroes

Features
Read full description

Turn algorithms into weapons. Turn sorting into ultimate moves. Algorithm Heroes is a Roguelike tower-climbing game that blends algorithm learning with card-battle combat. Here, Bubble Sort becomes "Bubble Slash," Quick Sort becomes "Quick Partition," and Binary Search becomes "Binary Arrow" — every algorithm is a battle card, and every swap, comparison, and partition deals real damage to monsters. No memorization required. Understand algorithms naturally through battle. CORE GAMEPLAY: 100-Floor Algorithm Tower 5 chapters, each focused on a core algorithm, with escalating difficulty: · Chapter 1 [Bubble Wilds] — Bubble Sort (FREE) · Chapter 2 [Insertion Forest] — Insertion Sort (FREE) · Chapter 3 [Selection Valley] — Selection Sort · Chapter 4 [Quick Peak] — Quick Sort · Chapter 5 [Merge Sanctum] — Merge Sort A unique Boss guards every 20 floors: Chaos Slime shuffles your battlefield array, Pivot Demon can only be torn apart by divide-and-conquer algorithms, and Merge Dragon wields multiple enrage mechanics... You need to truly understand algorithms to exploit their weaknesses. 8 ALGORITHM CARDS — INFINITE STRATEGY · Sort: Bubble Slash, Insertion Pierce, Selection Strike, Quick Partition, Merge Fusion · Search: Binary Arrow (critical hit), Linear Scan, Hash Locate (ignores armor) Each card can be upgraded to Level 3. Chain same-type cards to trigger Combo multipliers up to 2x damage. Cards have synergy effects — sort first, then search for doubled damage! ROGUELIKE ELEMENTS — EVERY RUN IS DIFFERENT · Normal battles / Elite monsters / Boss fights · Shop: Buy new cards, upgrades, pets · Treasure rooms: Random artifacts · Rest rooms: Recover HP · Random events: Unexpected encounters 6 artifacts with passive bonuses: CPU Booster, Recursion Chip, Stack Overflow, Hash Table... Make every build unique. 6 algorithm pets assist in battle: Bubble Dragon auto-swaps inversions, Binary Fox locks onto target positions, DFS Wolf applies hunt markers... Collect pets and build your ultimate team. 3 ALGORITHM MINI-GAMES — LEARN WHILE YOU PLAY Beyond the tower, enjoy 3 casual algorithm mini-games: · Match — Clear the board with linear search, hash lookup, bubble swap, and sort compress · Snake — Eat numbers in ascending order using binary radar and BFS hints · Blocks — Drop number blocks, sort rows, and trigger clears Each mini-game features unique algorithm mechanics that build your algorithmic thinking naturally. DAILY CHALLENGES & ACHIEVEMENTS · Daily Challenge: Fixed seed, compete with friends · 12 Achievements: From "First Purification" to "Algorithm Hero" · 6 Ranks: Rookie Coder → Algorithm Apprentice → Algorithmist → Architect → Algorithm Master → Algorithm Hero · Shareable stats cards: Show off your tower-climbing record WHO IS IT FOR? · Students: Preparing for CS exams or coding interviews — learn algorithms the fun way · Programmers: Review sorting and searching algorithms while enjoying roguelike deckbuilding · Coding beginners: Zero foundation needed — understand algorithmic thinking through play · Teachers: Demonstrate algorithm execution step-by-step in class THEMES & PERSONALIZATION Multiple programmer color themes: Dracula, Monokai, GitHub Dark, Solarized, One Dark... Pick your favorite code style and take it to the battlefield. FREE TO TRY — PAY WHAT YOU WANT · Chapters 1-2 (40 floors) are completely FREE — includes Bubble Sort and Insertion Sort · Pro unlocks all 100 floors + all algorithms + all themes + pet pack · Or buy chapters, theme packs, or pet packs individually --- From Rookie Coder to Algorithm Hero — your journey starts here. Download Algorithm Heroes and make algorithms your weapon.
