# 选号下注
投注方式下注十分简单，类似传统产品中的Pick3, 任意选择3位数号码(000-999), 设置投注数量，使用$wUSDC支付后即可完成投注
1. 游戏逐轮进行，参与者默认投注到当前进行中的最新轮次；
2. 支付代币为通过AOX跨链过来的[$wUDSC,](https://www.ao.link/#/token/7zH9dlMNoxprab9loshv3Y7WG45DOny_Vrq9KrXObdQ) 最小投注额度为$1, 最大投注额度为$100, 无需支付Gas费（AO主网上线后可能会存在忽略不计的Gas,GAS消耗为$AO不包含在投注金额内），确认支付后投注成功；
3. 每一次投注都会生成一张永久存放在Arweave上的投注票据，相当于传统发行的彩票，存放在Arweave上的彩票是一种具有可发现性的原子资产，相当于NFT，具有收藏价值。[链上彩票示例](https://kmu4rbzchrloqp3ypunbd4y345hrhritxwufx7dg5ymkbce6anhq.arweave.net/UynIhyI8Vug_eH0aEfMb508TxRO9qFv8Zu4YoIieA08)
4. 铸币奖励和ALTb释放与Bet2Mint机制有关，铸币奖励是你完成投注后，协议奖励基础$ALT， ALTb释放是在基础奖励之上的Buff(加成)，铸币Buff是面向早期用户的额外奖励，不代表所有的参与地址都拥有，[了解Bet2Mint详情](/cn/usdalt.md#bet2mint)
投注完成后，等待开奖，开奖通知将会在Aolotto[官方X](https://x.com/aolotto_dao)和[Discord Server](https://discord.gg/BFhkUCRjmF)中实时发布，你也可以在[个人中心](https://aolotto.com/#/me?tab=wins)和[开奖页面](https://dev.aolotto.com/#/draws)中查询中奖或开奖历史。
## 最佳投注策略
Aolotto总共可以选择的号码为1000个，意味着每一次投注的中奖概率为1/1000， 并叠加了Bet2Mint机制，通常情况下，每一轮启动后，越早参与，通过Bet2Mint获得的$ALT奖励越高，越晚参与，中奖概率会更高（最后下注者中奖概率至少高出50%），基于这样的规则，我们推荐如下的投注策略：
1. 早期铸币奖励($ALT)高的时候，建议单次投注的金额设置为$100, 例如玩家A下注时，Bet2Mint单笔投注的铸币奖励为200$ALT, 投注$1获得奖励为200$ALT, 投注$100,得到的铸币奖励为20000 $ALT, 下一个参与者玩家B参与时，Bet2Mint单笔投注的奖励则下降为（本轮铸币余额-20000）\* 0.0001；
2. 后期参与者，可以考虑使用最小投注金额$1参与竞争最后投注者。
