Boost Casino: the facts

100 spins with a 72-hour clock

New players in Finland get 100 free spins on Razor Ways, a Push Gaming slot, once a first deposit of at least €30 lands. Each spin is worth €0.20, so the whole bundle is €20 of stake. Whatever the spins win then needs 30x wagering before it can leave the account, and the clock is short: 72 hours.

Two more terms shape what you can take home. Spin winnings are capped at €1,000 when you cash out, and while the wagering runs, no single bet may exceed €5. The second detail hides an unusual rule: only €1 of each spin counts toward the playthrough.

The practical reading: the spins are a side dish on a deposit you were making anyway, and a heavy one to chase. If you cannot fit a few hundred spins into the next three days, let the bonus winnings lapse rather than raising your stakes to catch up.

Bank login instead of a sign-up form

Boost has no registration form. You choose your bank, sign in with your bank ID, and the first deposit creates the account. The record lists two services for this, Trustly and Zimpler. Finnish review sources each named a different one, so expect the cashier to show at least one of the pair rather than both.

Trustly describes its flow as picking it at checkout and then approving inside your bank app or with an eID. Zimpler, a Swedish payment institution that belongs to TrueLayer, moves money straight between bank accounts over open banking. Either way, withdrawals travel back to the account you paid from.

The record gives no stated payout time for Boost, so none is quoted here, and the payout sub-score of 7.0 is the lowest part of its score. If cash-out speed is what decides it for you, the fast payout casinos in Finland list is the better starting point.

Live chat answers in Finnish every day until 02:00, which suits evening players. Boost has also been running since 2020; among the casinos we list for Finland, only Ninja Casino is older, and most of the others opened in 2026.

An Estonian licence, shared with Ninja

The licence numbers on Boost's record, HKL000413, HKL000414, HKT000069 and HKT000070, come from the Estonian Tax and Customs Board (EMTA). They are the same four that appear on Ninja Casino's record. Estonian law asks for both an activity licence and an operating permit before a company may organise gambling, which is why there is more than one number, and EMTA publishes a list of the operators that hold them, so you can match the numbers yourself.

For a player in Finland, the EEA location is the whole point. The Tax Administration exempts winnings from gambling lawfully arranged in an EU or EEA state where the operator is registered and licensed, so Boost winnings are tax-free under that EEA rule as it stands. Our Finnish winnings-tax guide explains where the line sits and what changes for offshore sites.

What the Estonian licence does not do is bring Boost into Finland's own arrangement. EMTA supervises gambling in Estonia; in Finland, Veikkaus keeps its exclusive right until the end of June 2027.

Boost next to its Finnish rivals

Boost's €30 entry is the highest in this group. Kasarmi asks a third of it and pays its bonus-game spins at 1x; Hype's wheel needs €20 and 10x. SpinSkull looks bigger on paper, but its 40x counts deposit and bonus together. All five hold EEA licences, so the tax point does not separate them. The terms do.

Who Boost suits

Boost fits a player who wants an EEA-licensed site with Finnish chat late into the evening, plays slots in volume anyway, and can treat three days of 30x as part of normal play. It is a weaker fit for small budgets, for anyone after a big lobby (the record counts about 2,000 games), and for players who choose a casino on payout speed. The Boost Casino review covers the lobby and the rest of the site.
