What Is Speedrunning and Why Does It Matter

Speedrunning is the practice of completing a game — or a defined section of it — as fast as possible. What began as a niche hobby shared on obscure internet forums has grown into a major gaming subculture with dedicated streaming communities, annual charity events like Games Done Quick, and world records tracked to fractions of a second. HTML5 browser games have developed their own speedrunning communities, and the skills involved are genuinely fascinating to study even if you never compete yourself.

Understanding Speedrun Categories

Speedrunning is not one thing — it is a family of related practices defined by their rules:

  • Any% No Major Glitches — Complete the game by any means in the fastest time, excluding major exploits. The most accessible category for new runners.
  • Glitchless — Complete the game without using any glitches, relying purely on optimised movement and decision-making.
  • 100% — Complete all required objectives in the fastest time. Requires complete game knowledge.
  • Individual Level (IL) — Time individual levels rather than a full playthrough. Lower commitment and faster feedback loops make this ideal for beginners.

Core Speedrunning Skills

Frame-Perfect Execution

Many speed techniques require inputs at specific frames — one sixtieth of a second. Building the muscle memory for frame-perfect timing requires focused repetition — the same action, hundreds of times, until it is automatic.

Route Optimisation

The most significant time savings in speedrunning often come from doing things in a different order than a casual player would, or skipping sections entirely. Studying existing speedrun routes before developing your own is essential — you rarely discover significant optimisations that experienced runners have not already found.

Consistent Reset Discipline

When a run goes poorly, knowing when to reset and start fresh is a critical skill. Completing a bad run provides limited practice value; resetting and trying for a good run develops the habits that produce personal bests.

How to Start Speedrunning HTML5 Games

Pick a game you already know well and enjoy. Check Speedrun.com to see if it has an existing category. If it does, study the current world record run carefully before setting your first time. Record your first few runs with screen capture software so you can review your decision-making after the fact.
