Bonus Buy, also called Feature Buy or Bonus Purchase, is a slot mechanic that allows players to skip the base game entirely and pay a fixed multiplier of their stake, typically between fifty and three thousand times the bet, to trigger the bonus round immediately. The concept was popularised by studios like Nolimit City and Hacksaw Gaming and has become a defining feature of the high-volatility slot category. In a standard slot, reaching the bonus round requires landing a specific combination of scatter symbols, which can take hundreds of spins and significant base-game investment. The Bonus Buy mechanic removes that waiting period entirely, giving players direct access to the feature where the largest wins are concentrated. This is inherently controversial: it accelerates gameplay and increases spending velocity, which is precisely why the United Kingdom's Gambling Commission banned the feature at UKGC-licensed casinos in 2019. The ban remains in place, meaning Bonus Buy is unavailable to players at any UK-regulated casino. However, it is legal and widely available at casinos licensed in Curaçao, Malta, and other jurisdictions, and it has become a central selling point at crypto casinos.
Wanted Dead or a Wild from Hacksaw Gaming offers multiple Bonus Buy tiers, including a premium option that guarantees enhanced starting conditions in the free spins round, with maximum win potential reaching extraordinary levels. Mental from Nolimit City provides three buyable bonus options at different price points, each unlocking increasingly volatile feature combinations using the studio's xMechanic system. Money Train 4 by Relax Gaming allows you to purchase direct entry to its respin collector round, where persistent multipliers can stack to enormous totals. Sweet Bonanza from Pragmatic Play offers one of the most accessible Bonus Buy options at twenty-five times the stake via the Ante Bet. San Quentin xWays from Nolimit City features one of the most expensive Bonus Buy options in the industry, priced at over two thousand times the stake, reflecting the game's extreme 150,000 times maximum win potential.
Bonus Buy is not available at UKGC-licensed casinos due to the 2019 ban, so players seeking this feature will need to play at casinos holding MGA, Curaçao, or other international licences. Crypto casinos are particularly well stocked with Bonus Buy titles. The best providers for this mechanic are Nolimit City, Hacksaw Gaming, Relax Gaming, and Pragmatic Play. Most casino lobbies that offer the feature allow filtering by "Bonus Buy" or "Feature Purchase," and the option appears as a clearly marked button within the game interface itself.
