シーン	設定のコツ
罰ゲーム	罰の重さでランクを分ける（軽い罰=普通、大物=大当たり、セーフ=ハズレ）。割合を変えて当たりにくさを調整
席決め・順番決め	「当選した項目を自動で除外」をONに。回すたびに残りから抽選され、全員の順番が公平に決まる
プレゼント交換・景品抽選	景品名を登録して自動除外ON。目玉景品はランクを「大当たり」にすると当選時に紙吹雪とファンファーレで盛り上がる
会計・おごりルーレット	参加者名＋「割り勘」を登録。割り勘の割合を大きめにすると平和に収まりやすい
子ども向け抽選会	シークレット確率モードなら、見た目の確率はそのままで実際は必ず当たる設定も可能。誕生日会の演出などに

確率の変更・操作のしくみ

確率の変え方は2通りあります。割合変更は「割合」の数値を変える方法で、セグメントの幅（見た目）も一緒に変わります。3:1にすれば見た目も確率も3:1です。

シークレット確率モード（確率操作）は、見た目の割合はそのままに、実際の抽選確率だけを別に設定する方法です。「必中」を指定すれば、見た目30%の項目に100%当てることもできます。回す人には設定は見えません。

※ シークレット機能はサプライズやパーティー演出のための機能です。金銭・景品が絡む公正な抽選には使わないでください。

Party Setup Cheat Sheet

Scene	Setup Tips
Penalty game	Rank penalties by severity (light = normal, big one = jackpot, safe = miss) and tune the odds with weights
Seats & turn order	Turn on "remove winner automatically" — each spin draws from the remaining entries, so the order is fair
Gift exchange / prize draw	Register prizes with auto-remove ON. Set the grand prize rank to "jackpot" for confetti and fanfare
Who pays the bill	Add participants plus "split it". A larger weight on "split it" keeps the peace
Kids' prize draw	With secret odds mode, an item can look like 30% but always win — great for birthday surprises

How Odds Adjustment Works

There are two ways to change the odds. Weight adjustment changes segment size and probability together — 3:1 weights look and act like 3:1.

Secret odds mode keeps the visual layout unchanged while the actual draw uses separate probabilities. With "guaranteed win", an item showing 30% can win 100% of the time. Spinners can't see the settings.

* Secret features are for surprises and party fun only. Do not use them for fair draws involving money or prizes.

About Roulette Maker

Roulette Maker is a free online spinner tool where you set up your own items and spin the wheel. Use it for penalty games at parties, seat and turn order, gift exchanges, prize draws, or picking a lunch spot. Party presets for penalty games, seating, gift exchange, bill roulette, and cleaning duty come with ranks and weights preconfigured.

Fullscreen Party Mode

Party mode switches to a fullscreen view with just the wheel and a big START button. While spinning, the buttons disappear and the wheel ticks as it decelerates. Results are announced with rank-based effects: golden confetti and a fanfare for jackpots, a dramatic descending "womp" for misses. It works great on both phones and PCs, with three selectable jackpot sounds and a mute mode.

Two Ways to Control the Odds

You can change odds in two ways. Weight adjustment changes segment sizes and probabilities together — a fair, visible method. Secret odds mode keeps the wheel's appearance unchanged while the actual draw uses separate probabilities, including a "guaranteed win" option — an item showing 30% can win every time. Great for birthday surprises where a child always wins the prize. Please do not misuse it in draws involving money.

Turn Order, Sharing, and Saving

Turn on auto-remove and each spin draws from the remaining items — perfect for fair turn order and gift exchanges, with one-click restore. Copy a share URL to hand the exact same wheel to friends. Your setup is saved automatically in the browser, and everything runs locally — no data is ever sent to a server.
