How Copy Head Works
Copy Head uses eight fair binary symbols. The game scans left to right. At each unread position, it finds the longest matching substring contained wholly in the already consumed prefix. A match length of at least two is a copy token; otherwise, one literal is consumed.
One whole captured stake covers this complete independent fair binary word. The score is the total copied lengths minus one per copy token.
Scoring and Modes
Players choose one of three score powers: score, score squared, or score cubed. Each mode is separately normalized over all 256 equally likely words to 96% expected gross return.
A larger power does not change which words score zero. Powers one, two, and three do not alter which raw scores are zero.
Payout and Settlement
Gross = 0.96 × captured whole stake × raw^(selected mode + 1) / mean[selected mode]
Separate exact means:
- Power 1: 2.1015625
- Power 2: 4.9140625
- Power 3: 12.4609375
Expected gross return is 96%; this is not guaranteed net profit.
The formula uses mode index 0, 1 or 2 for Score, Squared or Cubed respectively; the exponent is therefore 1, 2 or 3.
Controls and Auto Play
- Auto10: Queues at most ten captured draws.
- Stop: Cancels future draws while the current one settles.
- Sound: Remains available during active settlement.
Settings and refill are locked until settlement and the queue finish. 480ms captured settlement occurs per draw.
Wallet and Persistence
Initial Balance: 1000
Restoration: Manual idle-only restoration when balance is below 10 sets the balance to exactly 1000. This does not add coins or automatic replenishment.
Fractional Carry: Persists across settlement, refill, and reload.
Reload: Ends an unfinished draw without refund or resume.

| [1,1,1,1,1,1,1,1] | 4 | actual game.js pure score function |
| [0,1,0,1,0,1,0,1] | 4 | actual game.js pure score function |
Frequently asked questions
Is Copy Head an official game from a verified operator?
This demo belongs to this independent guide. The queried name does not establish an official company, account address, app, or service. No external catalogue is verified.
How does the wallet restore balance?
Balance restoration is manual and idle-only. It triggers when the balance is below 10 and sets it to exactly 1000. It preserves fractional carry. It does not add coins or trigger automatic replenishment.
What happens if I reload the page during a draw?
Reloading ends an unfinished draw without refund or resume. The settled balance persists locally, including zero.
