What is a 400% Deposit Match Bonus?

Match bonuses are the pot of gold at the end of the registration rainbow. They allow new players to earn massive amounts of bonus funds in exchange for a deposit at a new casino site. While we are so used to scanning through 100% bonuses and 200% bonuses, players often overlook the benefits of a 400% deposit bonus.

These massive offers allow players to obtain their initial deposit amount four times in bonus funds. Luckily for newbies searching for a 400% bonus, our team at Casino Martini has created the ultimate guide, so you claim the full potential of one of these astronomical deposit bonuses.

Join us here as we reveal the best 400% casino bonuses in Canada and provide the ins and outs to go with it. Are you ready to claim a welcome bonus of a lifetime? Let’s get started.

What is a 400% Deposit Match Bonus?

400% welcome bonuses are presented to attract new players to a casino site. Over the years, these deposit bonuses have exponentially grown to some extortionately high bonus amounts. This is music to all high-rollers’ ears, as maxing out on a 400% welcome bonus can be extremely enriching.

Although aimed at high-rollers, online casinos have made 400% welcome bonus offers accessible to all newcomers with reasonable minimum deposit amounts. Even with the minimum deposit of just $20 at some online casinos, you can wager with an additional $80 in bonus funds.

Let’s take an example and break this bonus down a little further. If an online casino offers a 400% welcome bonus of up to $200 up first deposit. New players that deposit the maximum amount of $200 will receive 400% of this amount, leaving them with $800 in bonus cash plus their initial deposit amount of $200. The first deposit must be wagered before the bonus funds can be obtained at the online casino.

Online casino sites also provide 400% welcome bonus offers over a number of deposits. This can be broken down in various ways, often being 100% per day over 4 days. Make sure to check through the bonus terms before securing your first deposit to ensure the rules are suitable for you.
