## Description

Challenge World is a cognitive gauntlet built to find your limits.
  
  310 levels. 50+ challenge types. Every session different.
  
  You'll face memory grids, rhythm tests, spatial logic, pattern locks, voice challenges,
  estimation games, reflex traps, and dozens of mechanics you won't see coming. The game shuffles
  daily the same level plays differently every time.
  
  6 TIERS. RISING DIFFICULTY.
  Foundation is free. Prove you belong before you touch Synapse, Cortex, Nexus, Zenith, or Apex.
  Most players don't clear the third tier. A handful reach the top.
  
  YOUR IQ MOVES.
  Every level you pass raises your IQ score. Every fail costs you. Hints carry a penalty. The
  leaderboard is honest no grinding past it.
  
  HEAD-TO-HEAD MODE
  Challenge real players to 1v1 duels. Pick a topic, pick your opponent, prove it live.
  
  GAUNTLETS & BOSS LEVELS
  Every tier ends with a gauntlet 10 challenges, zero resets, zero mercy. One wrong answer sends
  you back to 1. Boss levels pull from your entire tier history. You don't skip them.
  
  Available in English and French.
