Deposited $150 and redeemed slot coupon. Met rollover, got to ~$4800 and requested payout. Slotastic claimed I violated their max bet rule and reset my balance to $150. They claimed 3 of my ~3500 bets were over the $10 limit. All my other bets were $5 or less.
Do not remember making any bets over $5, but it is possible I made a few by accident. Many games, when you reopen or refresh it, reset the bet to maximum which you may not notice immediately. However, if I had to guess, I toggled from a second browser back to my slot game and, in doing so, accidentally clipped a pay-line marker. If you do this, it activates every pay-line up to that pay-line which could give you 3 consecutive $11+ spins without noticing.
Their rule is worded, "The maximum bet for all bonuses (including cashback) must not exceed $10. Any winnings, plus bonus amounts derived from bets higher than this limit will be voided". All 3 of my over-limit bets were losers and thus I "derived" no winnings from them. I told them I was, from the beginning, aware of their terms and conditions and of the max bet rule. I had played all previous coupons according to them. I mentioned the ways that higher bets could happen by accident. I told them, "The second sentence of your rule implies that the repercussion for violating a max bet of $10 is that it voids all wins on such bets as well as all wins which can be concluded to have been "derived" from bets made from the money won on those bets. The fact that the second sentence of your rule is clearly designed to clarify the first sentence, implies that just having a bet on principle above $10 does not void your entire balance above the original deposit."
I suggested that they should be happy enough that I gifted them 3 automatic losers by accident. Their response was "Whether or not winnings were had from the specific bet, if bets above $10 are made when a coupon is active, the winnings are voided." They then chastised my "playing style", i.e., the 3 accidental bets, reiterated numerous times that I be familiar with the terms and conditions, and invited me to play their hottest slots.
When I escalated a ticket here at casinomeister. Slotastic simply echoed their position. Despite my admonishments, Slotastic has shown no interest in updating the wording of their rule to reflect how they actually act on it. Doing so could eliminate any ambiguity. Any ambiguity should benefit the party that didn't write the rules. Rules like a $10 max bet are designed to protect casinos from people who want to collect bonuses while minimizing the action they give back. They are not meant to be an arbitrary way to say "gotcha". I don't care what anyone says. Slotastic is not justified here karmatically or by the wording of their rules.
