350 is not very many questions. Why don't you just shuffle the list when the user starts the game and avoid duplicates altogether? This takes very little processing power (even a crappy mobile phone can do the operation in milliseconds) and minimal memory (store pointers or indexes to questions and not the question itself....the order can be stored in ...

A simple resolution would be to show a simple descriptive text which tells them what to do i.e. they need to atleast upload two images to continue. Here is a quick wire frame for that. Until the user doesn't add the required number of images keep the continue\save button disabled.

Instead of showing an empty list, show one with two placeholders that need to be filled before continuing - this shows the user that you're expecting at least two images. As real images are added, remove the placeholders.

Take one step deeper. How should you display the questions? One step deeper. Why are users playing your game in the first part? If they want to learn something, they should repeat. If they want to be entertained they should repeat only if getting a repeated question allows them to feel confident or gain an extra advantage as this will enable a ...

Clear buttons are normally provided when the field is being used affect a default view and the user is likely to want to return to that default. For example, to filter the list of all products in a catalogue and then to return to the unfiltered list. It's easier and more intuitive to click an explicit 'clear' button than it is to highlight the contents, ...

The examples you give are all achievable using first order set logic without the need for nested operations. They can be described using a form with 3 simple fields: Using this interface, the set operations you describe can be created as follows (click image to expand): If you also need nested operations, this is also doable...leave a comment and I ...

If it's a website that has a lot of products in many categories, showing the category is a good way to help the user find what they are looking for. Example: when a user is searching for: game of thr Game of thrones in books Game of thrones in DVDs Game of thrones in eBooks Game of thrones Game of throubles Game of three and so on..

On Windows, Ctrl is primarily used for shortcuts to menu commands. Alt is used for access keys in menus and dialogs. While these are sometimes considered as shortcuts, Microsoft sees this more as an accessibility feature. Windows Key is used for system-wide functions. Function keys can also be used for shortcuts, and there are a few standard Function keys ...

A key strength of Material design is that it is defined from abstract principles downwards. While specification does include definition of components, it is (a) not prescriptive, and most importantly (b) there is enough mid-level and high-level guidance that a designer can create a new component that fits in with the other Material design components. ...

I opted to implement a mix between the provided answers. There are now three states: 0 images have been added: 1 image has been added: 2 images have been added: Now there is always a placeholder. The placeholder is the same size as the other grid items and is always at the end of the list so the interface will not change drastically after ...

From your diagram, we can add a simple message next to the 'add bikes' button, stating "x images to go." or "1 of x images added." after an image is added. Additionally, to ensure that the user uploads the correct amount of images, we can disable the save button until the correct amount of images is reached.

Provided the control can be styled and made to behave within the guidelines of material style and consistent behaviour, I'd say use it. I get the impression that the Material Design guidelines are largely concerned with how an app appears and behaves, and doesn't necessarily prescribe a narrow list of controls you can choose from. In cases where you want ...

If your users are going to be able to answer the questions quickly, example: Which of the following is an Impressionist painter? (da Vinci, Rembrandt, Monet, Picasso) and they are going to quickly go to another problem then they will get duplicate questions very quickly. If they are using this trivia game in order to help learn a school subject they would ...

I can't really see the difference between this and a boolean rule/query builder, e.g. like the one described here. Let's use cars and look at your examples: Include red trucks. Include red cars and trucks as long as they're of Chevrolet make. Include red Chevrolets and Chevrolet trucks, but exclude vintage cars. download bmml source – ...

When people discuss haptic feedback (in relation to smart watches) like it's a new thing they are mainly talking about the feedback when people are actively touching the surface of the screen i.e when performing actions. In this instance I can't imagine there is a use to provide feedback whilst touching the screen that you have a message as if you are ...

There are two common patterns for clearing: explicit clearing, through a button, such as the included button you provided in your captures, or through a stand-alone button for the whole form. This latter solution tends to be a bad practice as users may press it instead of the submit button, and there are few use cases which require a clear form button. ...
