Build the selection deliberately
The visible grid contains numbers from 1 to 40, with an option to select between one and ten numbers. Use manual selections or the random-pick control, then inspect the highlighted numbers before betting. Changing the size of the selection changes which match outcomes the current paytable needs to cover.
Read the active paytable
Check the difficulty setting and number of picks together. A result with several matches can have a different value under another configuration. Look at the full table, including outcomes that return little or nothing. Do not carry a multiplier from a screenshot into a different set of selections and expect the same settlement.
Track settings alongside results
For a useful record, keep the bet amount, picked numbers, difficulty, drawn numbers and settled return. Random Pick is a convenience control, not a method for finding favoured numbers. Automatic betting repeats a configured selection process; inspect its stopping conditions and ensure that the selected options are the ones you intended.
