Most deposit bonuses are available every day. 22Bet's Sunday Mega Bonus deliberately isn't — it only activates on Sundays, rewarding that one day's deposit with a 66% match plus free spins, on the condition the whole thing gets wagered in a tight seven-day window.
The Sunday-Only Deposit Match
Making a deposit of at least 30 SGD (roughly 24 USD) on a Sunday triggers a bonus equal to 66% of the deposit amount, capped at 150 SGD (roughly 118 USD), plus a flat 50 free spins on top. Hitting that maximum bonus takes a deposit of around 179 USD-equivalent — anything deposited beyond that point still only earns the same capped bonus, so there's no additional benefit to depositing well past the threshold in a single Sunday transaction. The bonus is credited automatically the moment a qualifying deposit lands, unless the account has the "I do not want any bonuses" box checked, and only one Sunday Mega Bonus can be claimed per Sunday, not per deposit.
A Trap Worth Knowing About Before Depositing
There's a sequencing rule buried in the terms that's easy to trip over: making a withdrawal before making the Sunday deposit voids the bonus entirely for that day. A player who withdraws funds first and then deposits later the same Sunday, expecting the bonus to still apply, won't receive it — the withdrawal itself is what blocks eligibility, regardless of how the deposit that follows is structured.
Wagering: x40, Seven Days, Slots Only
Once credited, both the bonus funds and any free spins winnings carry a x40 wagering requirement, which needs to be cleared within 7 days and specifically inside the Slots section — wagering in other categories doesn't count toward clearing it. There's also a distinction in whose money is actually being wagered at each stage: while working through the bonus itself, every bet draws from the bonus account balance, but once free spins winnings are being wagered, that step uses the player's own funds instead rather than bonus money.
The Stake Cap While Wagering
A separate restriction applies for the entire duration of the wagering period: any single stake placed while working through the bonus cannot exceed 5 EUR (roughly 6 USD), or the equivalent in the account's own currency. A player trying to clear the requirement faster with larger individual bets runs into this ceiling regardless of how much bonus balance remains — the x40 target has to be reached through volume of smaller-stake spins rather than a handful of large ones.
A Long List of Excluded Game Categories
Wagering contribution isn't uniform across the casino — a substantial list of categories is excluded from counting toward the requirement entirely, including Roulette, Baccarat, Blackjack, Poker and its variants (Hold'em, Legion Poker), Keno, Bingo, Scratch Cards, Crash Games, Live Casino, Virtual Sports, Lottery, and Skill Games, among several others. What does contribute reliably is more straightforward: standard slot games count in full, at 100% contribution, which lines up with the requirement being restricted to the Slots section to begin with. Since 22Bet reserves the right to revise this exclusion list without prior notice, a game that contributes today isn't guaranteed to still contribute by the time a player is partway through their 7-day wagering window.
Worked Example: A Full Cycle
Say a player deposits 60 SGD-equivalent (roughly 48 USD) on a Sunday. That earns a 66% match — about 32 USD-equivalent in bonus funds — plus the standard 50 free spins. To clear the bonus, the player needs to wager 40 times that amount, or roughly 1,280 USD-equivalent, entirely within slot games, entirely within 7 days, with no single stake during that stretch exceeding the 6 USD-equivalent cap. Any portion still unwagered once those 7 days pass is simply lost, and once the requirement is fully met, any leftover bonus balance up to the original bonus amount moves over to the main account as real, withdrawable funds.
Bonus Type Exclusivity
The Sunday Mega Bonus is a casino-specific offer, and it can't be combined with a sports betting bonus on the same deposit — selecting a sports bonus instead means the casino version simply doesn't get credited. It also can't be used alongside any other 22Bet promotion running at the same time, and it isn't available on cryptocurrency-funded accounts at all, consistent with how 22Bet treats bonus eligibility across its other promotions.
