Choose a reliable casino

A 98% casino rating means it has passed our review and scored highly across over 30 parameters. We analyse ratings, bonus terms, payout fairness, transaction speed, support quality, game providers, whether RTP is lowered, licensing status, and more, checking every casino before listing it on our site.

ROI shows the potential profit on your deposit, including the bonus (e.g., 10% ROI = 10% profit). EV tells you, on average, how much you could win or lose from a bonus. These values take the guesswork out of picking the best bonuses. With our expert system, you’ll always know which bonuses are worth your time.

101RTP calculates RTP, EV, and other key metrics based on over 1 million simulations per analysis. We assess real gaming scenarios, factoring in bonus conditions, volatility, win frequency, and other hidden parameters.

Casino bonuses aren’t just «free money». Hidden conditions like wagering requirements or win caps can make bonuses less valuable. Calculating ROI and EV reveals their true worth, helping you spend wisely, plan better, and reduce losses.

Our system delivers accurate, detailed calculations, including ROI, EV, bonus wagering probability, volatility, and win distribution. You can personalize the results by entering your bonus details, and thousands of slot simulations ensure high accuracy. We also analyse win probabilities, losing streak risks, and big win distribution. This exclusive level of insight helps Kiwi players make smarter, more profitable decisions.
