How to Set Prizes and Winning Chances?

The slices on the wheel, that is, the prizes you will give out, are in the Session → Prizes tab. Each row is a slice on the wheel: the prize's name, how many will be given out, its chance of coming up, and, if there is one, its code and photo. This article explains how to fill in the prize list, how the chance is calculated, how the quantity limit works and how to reset the counter after test spins.

The prize list

Each row in the table is a slice on the wheel, and the slices are arranged on the wheel in the order of the table.

Add slice opens a new row; when you reach 12 slices the button is locked. The cross at the end of a row (Remove slice) deletes the slice; it cannot be deleted when 4 slices remain. You can write the same prize on several slices; in the ready-made set every prize appears twice.

In a new event the wheel comes with a ready-made set of 8 slices: Prize 1, Prize 2, Prize 3 and Grand Prize. Meanwhile the tab shows the warning No slices defined yet — a placeholder set is being shown to guests. Set your real prizes here. Once you write your own prizes and save, the warning goes away.

Changes are not saved while you type. Press Save; the text Saved appears next to the button. If you leave the tab without saving, what you wrote is lost.

How the chance is calculated

A prize's chance of coming up is its own number divided by the sum of the numbers of all slices. For a prize without a quantity this number is Weight; for a prize with a quantity it is the remaining quantity. The wheel draws every slice at the same width; the guest cannot tell which prize is rare by looking at the wheel.

Example, the ready-made set: the two Prize 1 slices have a weight of 30 each, the two Prize 2 slices 22 each, the two Prize 3 slices 8 each and the two Grand Prize slices 2 each; the total is 124. The chance of one Prize 1 slice is 30/124, about 24%. The chance of one Grand Prize slice is 2/124, about 1.6%.

The Chance column does this calculation for you and shows each prize's current percentage. When you change one weight, the percentage of every row changes, because the total changes.

The quantity limit

If you write a number in the Quantity field, at most that many of the prize will be given out during the event. If you leave the field empty, the prize is unlimited.

For a prize with an Quantity, Weight is not used; the remaining quantity decides the prize's chance. A prize with a quantity of 100 starts with a weight of 100; when 40 of it have been given out, its weight drops to 60. This way, as the prize runs low its chance of coming up decreases by itself, and when the stock runs out it drops to zero.

A prize whose stock has run out does not disappear from the wheel: the slice stays in place but the wheel does not stop on it. The guest is not told separately that it has run out.

If the quantity of every prize runs out, the warning Every prize is out of stock. The wheel cannot be spun until you raise a quantity. appears in the tab and the SPIN button does not work on the guest screen. To prevent this, leave at least one prize unlimited; a small consolation prize is good for this.

Be careful when you use prizes with and without a quantity together: they compete in the same total. Next to a prize with a quantity of 100, an unlimited prize with a weight of 1 almost never comes up. Look at the Chance column before saving.

Code and QR

The text you write in the Code field is shown on the prize panel to the guest who wins that prize; below it, it says Show this code at the stand. The code belongs to the slice: everyone who wins the same prize sees the same code; no personal code is generated.

For a prize with a code, the panel also shows a QR. The QR takes the guest to the prize's web page; for this the record must have reached the cloud, that is, the device must be connected to the internet. You can turn the QR off with the Game Screens → Wheel → Show QR on the result screen switch.

If the code field is empty, the panel shows the note No code is set for this prize — please collect it from the staff. instead of a code and QR.

The prize image

If you touch the box in the Image column and choose a photo, the photo appears on that slice together with the prize's name. The cross in the corner of the box removes the photo. How the photo sits on the slice is not chosen in this tab but in the Game Screens → Wheel → Slice image section.

Resetting the counter

The remaining quantity is calculated by counting the prizes won in the event; the test spins you made during setup are counted too. Press Reset counter before the event starts. The Reset the prize counter window opens; you confirm with Reset and cancel with Cancel.

After the reset, the remaining count starts again from the quantity. No record is deleted: the test spins stay in the Winners list, and you can remove them from there with Hide. If no prize has been given out yet, the button is faded.

Multiple kiosks

If you run the same event on several devices, the quantities are shared: wherever a prize is won, it is deducted from the same stock. The count lags by about 30 seconds between devices; because of this two kiosks can give out the last prize at the same time and the quantity can be exceeded by one or two. When you reset the counter, the other kiosks are reset within about 30 seconds too. All of this requires the devices to be connected to the internet.
