How Unlimited Multipliers Work (1,000-Point Max Score)
Every Unlimited run escalates across 5 difficulty bands with progressive score multipliers: Round 1 (Easy, ×1), Round 2 (Easy, ×1), Round 3 (Medium, ×2), Round 4 (Hard, ×3), and Round 5 (Hard, ×3).
Because Rounds 4 and 5 carry a 3× multiplier (worth up to 300 points each), nailing your late-game scale estimates can propel your run to a perfect 1,000-point score. Want to compare against everyone worldwide on today’s fixed seed? Switch to the Daily Challenge anytime.
