Octalysis: the eight Core Drives
Yu-kai Chou's practitioner framework holds that every action is powered by at least one of eight Core Drives, placed on an octagon whose geometry signals each drive's nature: top drives empower, bottom drives create urgency, left drives lean extrinsic and right drives intrinsic. It grew from years of observing games, not from experiments.
Plain label: eight-motivation frameworkAlso known as: Octalysis, Core Drives, Octalysis Framework
What it claims
Chou's central claim is that no action happens without at least one Core Drive behind it, so a funnel step with no drive is a predicted drop-off. Points, badges and leaderboards are the visible shell; the drives are what actually move people. Design starts from the feeling and the Desired Action, never from a menu of mechanics.
The eight drives
| Code | Core Drive | Plain gloss | Hat | Brain side |
|---|---|---|---|---|
| CD1 | Epic Meaning & Calling | being part of something bigger, or feeling chosen | White | none (top) |
| CD2 | Development & Accomplishment | progress and mastery over a real challenge | White | Left |
| CD3 | Empowerment of Creativity & Feedback | trying combinations and seeing results | White | Right |
| CD4 | Ownership & Possession | things that feel like yours | Dual | Left |
| CD5 | Social Influence & Relatedness | what other people do, think or say | Dual | Right |
| CD6 | Scarcity & Impatience | wanting what you can't have yet | Black | Left |
| CD7 | Unpredictability & Curiosity | not knowing what comes next | Black | Right |
| CD8 | Loss & Avoidance | avoiding the loss of what you have | Black | none (bottom) |
Outputs always show a drive with its name and plain gloss, never the bare code. The two axes are explained in White Hat vs Black Hat and Left Brain vs Right Brain. Chou also names a hidden ninth drive, Sensation (physical pleasure), which he leaves out of the framework and treats only as a reward or feedback element.
How it is used
- Rate per Desired Action. Each drive gets a 0-10 rating for how strongly it moves one Desired Action in one phase, with evidence for each rating.
- Read the shape, not the total. Chou's Octalysis Score sums the squared ratings (0-800), so a few strong drives beat many faint ones. He calls the score a gimmick; the useful output is which drives are absent, which are strong, and their hat and brain-side mix. Adding a touch of an absent drive is cheap; pushing a strong drive from 8 to 9 takes experts and testing.
- Watch for inflation. Teams tend to rate their own product 7-9 on everything, which would mean out-engaging the biggest social networks.
- Levels. Level I is the eight drives; Level II repeats them for each of the four Experience Phases; Level III crosses phases with user segments. The book teaches only these three levels, and Gamify It makes no claim about anything beyond them.
- Strategy first. Chou defines the Strategy Dashboard before choosing any technique.
How much to trust it
Octalysis is a practitioner framework, grade Evidence grade D. Practitioner framework or anecdote: plausible, untested.. Chou built it over about ten years of studying games and checked it against research afterward. His benchmark scores are subjective, and "Left/Right Brain" is a metaphor, not neuroscience. Gamify It uses the drives as a design vocabulary and a diagnostic lens and tests their predictions on each product's own data.
