When adding a new ticket inputs accepts all the possible ticket values from 01 to 75, but the each column should have the limited range of numbers accepted.

1st column: 1-15
2nd column: 16-30
3rd column: 31-45
4th column: 46-60
5th column: 61-75

Ticket component is huge because it has isEditable prop which makes the component very functional and hard to maintain. Besides that, it requires having a lot of requiredIf in prop-types.

Expectations

Have either two different components (Ticket (view only) and EditableTicket(with handlers)) or make EditableTicket a wrapper for Ticket.

All tickets have their numbers next to them, but there may be much easier to check and compare them when having then next to each other.

Expectation

List may possibly be at the right bottom of the app, listed with monospace font-face.

The current solution has the status message appearing to the right of the input and showing the message until the new message kicks in or reset.

Expectation

• Have dynamically appearing status bar for limited time (f.e. 5 seconds)
• Responsive friendly solution, so it is convenient to play the lottery on mobile devices

Issue

Any input in the app (the main top one and in the add ticket modal) accepts both 0 and 01-like inputing and they are both treated the same.

Expectation

All the inputing should have only integer inputs and 01-like numbers in the app are formatted to be read-only values.

The current app structure is robust and having a lot of passing handlers as params, so it becomes harder and harder to maintain the app.

Expectations

• Split app structure to logical container components and have them enhanced with redux.
• Simplify the app, having everything modularised and easier to maintain.
• Have app state in react-redux instead of having it in the App.js

When one ticket is added using ModalCreateTicket, the next time you want to add a ticket it has the old state.

Having information about total rolled balls amount may help when playing the lottery.

Add the following win patterns highlighting in tickets:

• corners
• middle row
• diagonals

According the rules of game the win patterns above applies until the 38 ball is rolled out.

Add version indication could be added to the app.

It does not really matter whether it is visible in the app, or added to the sessionStorage key, but it should be possible to identify the version, without looking at the source code.
