Actionable Gamification · Yu-kai Chou
The eight Core Drives
Eight reasons people act, from meaning and progress to curiosity and fear of loss, and how to tell motivation that lasts from pressure that burns out.
Octalysis sorts what motivates people into eight Core Drives. Points, badges and leaderboards are only the surface; the drives underneath are what move people.
Drives at the top of the octagon make people feel good and in control (White Hat); drives at the bottom create urgency (Black Hat). Both work, but they last differently, which is why we track the mix.

eight-motivation framework
In plain English
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.
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.

Each drive with its plain meaning, where it sits on the octagon, and the techniques in our library that use it.
01
CD1 Epic Meaning & Calling
White Hat
Feeling part of something bigger than yourself, or chosen for it.
The drive to act because you serve something larger than yourself, or because you feel chosen for it. Chou calls it the prime White Hat drive: it strengthens the other drives and earns forgiveness, but it is hard to make believable and creates no urgency, so people agree and then put things off.

CD2 Development & Accomplishment
White Hat · Left Brain
Making progress, building skill and beating a real challenge.
The drive to grow, master skills and overcome real challenges, including feeling smart while using a product. It is the easiest drive to design for, which is why points, badges and leaderboards cluster here and why it is overused: showing progress is not the same as feeling accomplished.

CD3 Empowerment of Creativity & Feedback
White Hat · Right Brain
Trying ideas, combining things and seeing what happens.
The drive to take part in a creative process: combine tools into a strategy, see the result right away and adjust. Chou calls it the golden corner because it is both White Hat and intrinsic, and the main source of evergreen engagement; it is also the hardest drive to build and costs attention new users rarely have.

CD4 Ownership & Possession
White or Black Hat · Left Brain
Wanting to protect, improve and add to what feels like yours.
The drive to improve, protect and gain more of what feels like ours: profiles, workspaces, collections, currencies and systems that learn us. It is the most extrinsic drive and sits in the dual middle band, empowering when it gives control and Black Hat when possessions start to own their owner.

CD5 Social Influence & Relatedness
White or Black Hat · Right Brain
Acting because of what other people do, think or say.
Everything people do because of others: mentorship, acceptance, social feedback, companionship, competition, envy and shared norms. It amplifies most other drives and sits in the dual middle band: White when it brings friendship and help, Black when it turns into peer pressure, spam or toxic competition.

06
CD6 Scarcity & Impatience
Black Hat · Left Brain
Wanting something more because you can’t have it yet.
The drive to want something because it is rare, exclusive or not available yet. Chou rates it the most volatile quadrant, Black Hat and left-brain: strong for launch bursts and closing moments, weak for long engagement, and it drives obsession rather than enjoyment. Goals that look impossible flip it into dismissal.

CD7 Unpredictability & Curiosity
Black Hat · Right Brain
Needing to find out what happens next.
The pull of the unknown and of chance: surprises, mystery rewards, draws and open questions. Chou classes it as Black Hat yet intrinsically thrilling, the Black Hat drive with the most staying power; it is also the main drive behind gambling, and combined with scarcity or loss it turns obsessive or anxious.

CD8 Loss & Avoidance
Black Hat
Acting to avoid losing what you have or missing out.
The drive to avoid losing what we have, wasting what we invested, or missing a fading opportunity. It is the purest Black Hat drive: strong at critical moments, corrosive when spread everywhere. Chou's rules are to apply it only at a few critical bumps, keep executed losses small, always offer a remedy, and return to White Hat.

White Hat vs Black Hat drives
empowering vs urgent motivation
Octalysis splits the octagon vertically: White Hat drives (CD1-CD3) make people feel powerful and fulfilled but create little urgency; Black Hat drives (CD6-CD8) create urgency and obsession but leave a bad aftertaste. CD4 and CD5 can tip either way. Chou's rule: Black Hat for breakout, White Hat for longevity.
- Framework · OctalysisEvidence grade D. Practitioner framework or anecdote: plausible, untested.
Left Brain vs Right Brain drives
extrinsic vs intrinsic tendency
Octalysis splits the octagon horizontally: left drives (CD2, CD4, CD6) lean extrinsic and goal-driven; right drives (CD3, CD5, CD7) lean intrinsic and process-driven. Chou says the labels are a metaphor, not neuroscience. His rule: lure with extrinsic rewards if needed, then move people toward right-brain motivation.

The four Experience Phases
discovery, onboarding, habit and veteran stages
Chou divides a user's journey into Discovery (why try it), Onboarding (learning the rules and feeling smart), Scaffolding (the repeated journey toward goals) and Endgame (why veterans stay). Motivation on day one is not motivation on day one hundred, so each phase needs its own drive design; Level II Octalysis rates the eight drives in each phase.
- Framework · Octalysis
Octalysis Strategy Dashboard
metrics, users, actions, feedback and rewards defined first
Before choosing any technique, Chou defines five things with every client: ranked Business Metrics (the Game Objective), Users (players and segments), Desired Actions (Win-States, by phase), Feedback Mechanics (each acting as a trigger) and Incentives (rewards ranked from abundant to scarce). Anything that drives no Desired Action is cut.
- Framework · Octalysis
Level III Octalysis: segments and player types
motivation profiles by user segment
Level III crosses user segments with the four phases to find where each segment's motivation breaks. Chou maps Bartle's player types to drives (Achievers CD2+CD6, Explorers CD7, Socializers CD5, Killers CD2+CD5), while noting every drive moves everyone in different proportions. Bartle himself doubted his types fit settings people don't choose.
