Abjad reckoning
Type any name, word or phrase and see what it adds up to.
Every Arabic letter has a number. The total is those added together — the working shows each letter so you can check it yourself.
Type the word as it is written, not as it sounds — spelling is the whole calculation. Before trusting a total, read the letter chips and check they are the letters you meant; a single wrong letter can move the number by hundreds. Where a chip is marked as changeable, the reading is genuinely uncertain and yours to settle.
