Bet unit is one of the terms that appears on every casino page and is explained on almost none of them.
Bet unit (also called stake size) — The amount staked on a single spin or hand, sized as a fraction of a bankroll rather than chosen as a number on its own.

A bet unit is the practical lever that connects a bankroll — the total set aside for play — to how long a session can last and how much variance it can absorb. The same peso figure can be a conservative bet unit against one bankroll and a reckless one against another; the unit only has meaning relative to the total it is drawn from and the volatility of the game it is being staked on.
A worked example
A ₱2,000 bankroll staking ₱20 per spin — a 1% bet unit — can absorb roughly 100 losing spins before running out. The same bankroll staking ₱100 per spin — 5% — can absorb only 20. On a high-volatility game, where dry runs of 80 spins or more are unremarkable rather than unlucky, the second sizing runs out well before the game has had a realistic chance to pay.
The common misreading
A small-looking bet unit is often assumed to be safe by default. It is not, in isolation. Safety is a relationship between the bet unit, the bankroll, and the game’s volatility — ₱10 a spin is trivial against a ₱5,000 bankroll and can exhaust a ₱50 one in a handful of rounds.
A bet unit is not the bankroll itself, and it is not volatility. It is the sizing decision that sits between the two — the bankroll is the total at risk, volatility is the game’s payout shape, and the bet unit is the choice that determines how many rounds the bankroll can survive against that shape.
Using it in practice
Set the bet unit as a small fraction of the bankroll rather than as a round number chosen out of habit, and reduce it further on higher-volatility games instead of keeping it fixed across every title played. It is easier to hold onto alongside how bankroll management works and the volatility entry, which the same pages tend to mention in the same breath.
Terms like Bet unit run through the game pages on this site, and where the studio does not publish the figure behind one, those pages say so instead of quoting a number from a comparison site. That is why several spec tables here carry blanks.
