Use affordable units
Only risk money you can afford to lose. Keep stake sizing small relative to bankroll and daily exposure.
Risk first
Betting is optional. Risk control is not.
SPK is designed to make uncertainty and exposure visible, not to encourage chasing losses or guarantee profit.
Never chase
A losing run does not make the next pick more likely to win. Stop when limits are reached.
Check local law
You are responsible for age requirements and the legality of betting where you live.

If betting affects finances, work or relationships, stop and contact an independent gambling-support service in your country.
