A bonus is a contract with a price. These guides put the price in NZ dollars: what the wagering turns into, which rule voids a win, and how often a simulated player gets anything out. Every number is either from the offer wording we quote or from a model we describe next to it.
Most casino bonus pages stop at the headline: a percentage, a cap, a number of spins. The cost sits in the terms underneath, and it is usually expressed as a multiple of something. Wagering of 40x on a bonus means forty times the bonus has to be staked before a withdrawal, and every spin at an average return below 100% gives some of that back to the house. These guides turn the multiples into New Zealand dollars so two offers can be compared on the same footing.
We read the rules that decide whether a win is paid: the maximum bet while a bonus is active, how games count towards wagering, and whether the bonus money is spent before or after your own. Where a figure comes from a simulation we say so next to it and state the assumptions, so you can rerun the sums with your own stake.
None of this makes a bonus a good idea. It tells you what you are agreeing to, which is the part the banner leaves out. If you only want the short version, start with the guide on wagering below; the rest go deeper on one rule each.
