There are a number of virtual dice, coin, and spinners available on the web. A quick google search can easily reveal them. The ones listed below lend themselves to mathematical teaching or are adjustable by the teacher or student.
Web Link: Adjustable Spinner
Flexibility: Provides an adjustable spinner for 1 to 12 sections. You can decide how many times the spinner is to spin (up to 1000) and the applet will track each spin result on a chart. Although you can only do 1000 spins each time, you can spin multiple times to keep adding to the chart. Each colour on the spinner will be given an actual and a theoretical percentage. You can skip to the end and do not have to watch each spin. You can also see a pie chart of the results at the end.
User Interfaces: Mouse and touchpad friendly. Intermittently touch-friendly, sometimes the size of the sections do not want to change with touch.
Browsers: Works with all major browsers.
Web Link: Interactivate: Adjustable Spinner
Flexibility: This virtual manipulative allows you to set the spinner from 1 to 12 sections. It also allows the user to set what theoretical probability each colour should have. The user can set it to run from 1 to 100,000 times. However, future spins tally on the last spins, so more than 100,00 spins are possible. The applet tracks what the actual number of stops on each colour were and provides it in a chart to the right of the applet. After spinning, the user is able to see the experimental graph as opposed to the theoretical graph (the spinner).
User Interfaces: Mouse and touchpad friendly. Works with touch, but the touchpoints are small and hard to adequately touch.

Web Link: Dice
Flexibility: This applet allows you to drag out 6 dice initially. After a die is dragged out its colour can be changed and the die can be cloned. There is an option to roll one die at a time or to roll all dice. There are 6 colours that the die can be set to. A toggle allows the die to be swapped between dots and numbers.

Web Link: Dice Tool
Flexibility: This applet allows you to drag out as many dice as you want. Each dice can either use dots or numbers 1 to 6. There is an option to colour dice red, green, or white which is great for probability. All dice are rolled at one time, there is no option to roll only one die.
