How "rigging" actually works here
This site doesn't secretly weight results — every spin is picked first by crypto.getRandomValues(), completely independent of the animation. What you can do honestly is set slice weights yourself: in this example, Big Prize has a weight of 1 against 24 total weight, so it lands about 4% of the time, while each consolation prize (weight 6) lands about 24% of the time. The wheel resizes each slice to match its real odds, so what you see is exactly what you get — no hidden thumb on the scale. Streamers use this for tiered giveaways; teachers use it for weighted reward systems.
