How to use and verify
Choose the currency, total and share increment, then add each participant individually. Enter also adds a name; the × button inside each name tag removes it. Add 2–30 people with distinct names of up to 80 characters. Adding or removing a participant clears the current round and its revealed results. Changing the total, currency or increment also clears the round.
Default increments are KRW 100, USD/EUR/CNY/GBP 1, JPY 100, VND 1,000 and KWD 0.100. These editable party-game suggestions draw on official denominations and local payment guidance; they are not universal minimum cash units or statutory rounding rules. Shares are generated as integer counts of the selected increment and converted back, preserving the exact total. If the total is not a multiple of the increment, generation is blocked and the remainder is displayed. For example, KRW 20,050 cannot be divided exactly in KRW 100 increments: adjust the total or increment yourself. KRW, JPY and VND accept integers, USD/EUR/CNY/GBP two decimals, and KWD three. Total and increment must be positive and at most one billion minor currency units.
The total becomes an integer and random cut points divide it into shares. Zero shares and large individual shares are possible. Agree to these rules first. Not every possible partition has equal probability, but shuffled assignment gives every participant the same expected share. Cryptographic randomness and unbiased integer sampling are used.
Create round fixes the outcome once. The ladder shows actual adjacent swaps. Roulette stops on the next participant’s assigned slot. Switching presentation modes or revealing another person never redraws the result. After everyone is revealed, compare the sum with the original total. Changing participants, currency, total or increment clears the round.
Only creating a new round generates a new result. Agree on redraw rules in advance. This is a local party game without payment or transfer processing. Copy the final record and compare it with the receipt before settling.
Names appear as compact tags; remove a person with the × inside the tag. After creating a round, Shuffle order changes only the order of people not yet revealed. The numbered reveal list immediately shows the new order and next participant. Previously revealed people, their results, every assigned share and the ladder mapping remain unchanged. Shuffling is disabled during a reveal animation and when fewer than two people remain. A random shuffle can return the same order; this is explicitly reported. Only a new round redraws the shares.
2026 example: USD 20.00 → 3.00 + 0.00 + 17.00 = 20.00
