Feature buys look simple on the surface: pay a fixed price, skip the base game, drop straight into the bonus round. The maths behind sizing them is less obvious, because the buy price scales with your stake and the same round can cost you ten cents or several hundred euros depending on which table you are sitting at. This guide sets out a repeatable method for capping each buy against your session bankroll, starting with the 5% rule and working through table minimums, game selection and the limits that sit behind the lobby.

Setting a buy budget before you touch the lobby

The core principle is straightforward: no single feature buy should cost more than 5% of your session bankroll. If you sit down with €200, your ceiling per buy is €10. If you bring €500, it is €25. That cap does two things. First, it keeps you in the game long enough to see a reasonable sample of bonus rounds, which matters because feature buys are volatile by design and a short run of bad outcomes can wipe a poorly sized budget. Second, it forces you to check the buy price before you commit rather than after, which is where most players get caught out.

Feature buys lock in a fixed cost and skip the base game entirely, so the price you see is the price you pay. That transparency is useful, but it also means the buy is a single, concentrated bet rather than a spread of spins. Treat it as one position in a portfolio, not as a shortcut to a bigger session. A player who buys ten rounds at 10% of bankroll each is effectively all-in after ten outcomes; a player who caps at 5% gets twenty attempts for the same money and a far smoother ride.

The buy price scales with your stake, and this is the detail that changes everything. On a game show with a €0.10 minimum, the cheapest buy might cost a couple of euros. Raise the stake to €5 and the same buy can cost a hundred times more. Before you set your 5% figure, confirm the table minimum, because that minimum determines the floor of what a buy can cost and therefore how many buys your bankroll can absorb.

Matching the buy to the table and the game

CasinoLab live casino offers hundreds of tables operating around the clock, and the spread of minimums across that lobby is wide. CasinoLab roulette starts wagers at €0.10, which is the kind of floor that keeps a feature buy genuinely affordable. CasinoLab blackjack sets minimum bets around €1 to €5, a different profile entirely. Game shows sit somewhere in between, and at https://casinolab-online.uk/live-casino/ the game shows accept fractional wagers, so you can often find a stake that puts the buy price inside your 5% cap without dropping to the absolute minimum.

Work from the buy price backwards. Say your cap is €10. If a game show buy costs twenty times your stake, your maximum stake is €0.50. If it costs forty times, your maximum stake is €0.25. Check the table minimum against that figure. If the minimum is €0.10, you have room. If the minimum is €1, the cheapest buy is €20 or €40 and your €200 bankroll cannot support it under the 5% rule. That is not a reason to break the rule; it is a reason to pick a different table or a different game.

Where the high-limit tables fit

Gold Saloon is reserved for high-limit play, and its banner tiles display a highest limit of €20,000. That is a different universe from the €0.10 roulette floor, and it is not the place to test a 5% sizing method for the first time. A feature buy at those stakes can run into four figures, which means the 5% rule only works if your session bankroll is genuinely large. For most players, the sensible approach is to learn the sizing method on low-minimum tables, confirm how buy prices behave at different stakes, and only then consider a high-roller table where the numbers are an order of magnitude bigger.

The Top Live section is a useful filter here. It surfaces the games drawing the most action, which usually means a spread of stake options rather than a single fixed buy price. Evolution and Pragmatic Play stock live titles from the lobby, and both studios publish buy prices as multiples of stake, so the arithmetic is consistent across their catalogues. Once you know the multiple, you can size any game in the section against the same bankroll figure.

Game selection matters as much as stake selection. Crazy Time and Lightning Roulette are the headline names, and both sit behind buy options that skip the base game. An augmented reality game show with a multiplier wheel can produce extreme outcomes from a single buy, which argues for the lower end of your 5% range rather than the top. Speed baccarat and squeeze baccarat are not feature-buy products in the same sense, but they belong in the same session budget, and if you are spreading money across game shows and live tables, the 5% cap should apply to the whole session rather than each product in isolation.

Two operational details are worth building into your routine. First, check whether the table offers a live cashback promotion. CasinoLab promotes a 25% live cashback, and cashback changes the effective cost of a buy, which in turn changes how much of your bankroll a single buy really consumes. Second, remember that CasinoLab runs in the phone browser without an app or APK, so there is no download barrier to checking a buy price mid-session. No-download mobile play makes it easy to compare the minimum stake and buy price on two or three tables before you commit, which is exactly the comparison the 5% rule depends on.

Side bets deserve a mention because they compete for the same budget. The CasinoLab blackjack interface provides side bets such as Perfect Pairs, and a Perfect Pairs side bet is a concentrated wager in much the same way a feature buy is. If you are running a session that includes both, count the side bet against the same 5% cap. A buy plus a side bet plus a few base-game hands can add up to a meaningful slice of bankroll without any single decision looking reckless.

Put the method into practice with a simple sequence. Set your session bankroll and calculate 5% of it. Open the live dealer lobby and note the minimum stake on each table you are considering. Divide your 5% figure by the buy multiple to get your maximum stake, then check that maximum against the table minimum. If the minimum is above your maximum, move on. If it fits, buy once and reassess. Keep a running total so that a string of buys does not quietly breach the cap. On a €200 bankroll with a €0.10 minimum and a twenty-times buy multiple, you are looking at a €2 buy, which leaves room for a hundred attempts under the 5% rule. That is the kind of margin that lets a volatile game show round play out without threatening the session.
