About this guide
About Iris Vale
Iris Vale writes and hosts Which Card, the guide to which rewards card works at which Ontario casino. She is a drawn character in watercolour, not a real person, and the site says so plainly.
What she does
On the home page, Iris Vale appears beside the card map, which colours each casino by its confirmed rewards card. She also sits next to sections across the site, with short notes on what each part covers. Her work behind those notes is plain: she matches every casino to its rewards card.
Photos of the casinos are used under free licences and credited under each photo. Where no free photo is in use, Iris stands in for the casino. In that picture she holds a board with the name of its card, so the page still shows which programme works there.
How she checks
For each casino, Iris Vale takes the rewards programme that the casino's own page or its operator's programme page names. Each check carries a date. Facts on the site were checked between October 7 and October 9, 2026, and every page shows the date of its check.
Where no official page she read names a programme, the guide says the card is not confirmed and names none. Casino Rama Resort is one such case. The casino itself can say which card it uses.
Who pays for the site
Which Card is an independent guide, not a casino: it takes no bets and has no accounts. Casinos, rewards programmes, OLG, the province and help services never pay the site. Only the home page carries paid links, marked Ad, and inner pages like this one carry none. Those links all lead to one online casino partner, which can change, and the site earns a commission. They are for Ontario only, so players must be physically located in Ontario.
