假如你发布了一款极有盈利潜力的免费增值游戏，下一步就是尽量排除应用内置付费过程中出现的用户偶然付费的情况。

1.设置合理的价格点

价格点是第一步要考虑的问题。虽然将封顶价格点（游戏邦注：例如大于49.99美元的价格点）移除听起来有点不合逻辑，但要知道那些有意购买价值100美元以上虚拟商品的用户，可以通过多次购买完成交易。删除封顶价格可以减少用户意外叠加付费的情况，49.99美元的多次累积消费额，并不像99.99美元售价叠加得那么快。

另外要注意的是，必须标注虚拟商品的售价是以真实货币来衡量。

以下是详细标注应用内置付费流程的游戏案例：

界面直接显示应用内置付费菜单(from smartappmarketing)

购物菜单同时显示真实美元售价(from smartappmarketing)

确认对话框中再次显示真实美元售价(from smartappmarketing)

以下是模糊标注应用内置付费流程的游戏案例：

购物菜单上没有显示真实美元符号(smartappmarketing)

仅在确认对话框中显示真实美元售价(from smartappmarketing)

2.透明的付费流程

显示相关详情有助于用户了解应用内置付费流程。做到以下三点可增加付费流程的透明度：

提供与常见付费问题有关的FAQ（疑问解答）服务；

在游戏中植入苹果客服支持网站以及付费条款链接；

在游戏应用和网站中嵌入你的客服支持联系信息。（本文为游戏邦/gamerboom.com编译，如需转载请联系：游戏邦）

Mastering Freemium Game Mechanics Series: Avoiding Inadvertent In-App Purchases

by Matthew Tubergen

Last week we discussed the importance of user retention and outlined some key steps for optimizing your reward schedule, an element every successful freemium game needs. Once you’ve established a game that can be strongly monetized you’ll want to make sure to add key elements to avoid, and easily resolve inadvertent in-app-purchases.

Freemium Game Mechanics: In-App-Purchase Price Points

The first step is to think through your price points. While it may seem illogical to remove your top tier price points ( > $49.99), it follows logically that those really intending to purchase $100 + in virtual currency can do so through multiple transactions. By removing the top levels you avoid the rapid accumulation of inadvertent in-app purchases. $49.99 accumulates slower than $99.99.

Additionally, always make sure you indicate the real dollar value when presenting virtual pricing.

Clearly State Purchase Price Examples

Access the in-app purchase menu.

Real dollar values are present at time of purchase in game menu.

Real dollar values are presented on confirmation screen.

Less Effective Purchase Price Disclosure

Real dollars are NOT shown at the purchase menu.

Real dollars are only presented on the confirmation screen.

Freemium Game Mechanics: In-App-Purchase Transparency

Disclosure is key to insuring the customer understands the in-app-purchase process. Here are three things you can do to increase transparency of in-app-purchase processes and support in your app.

Provide a mobile friendly FAQ along with answers to common billing questions.

Include links to Apple’s Customer Support Site and billing policies.

Provide clear contact information for your customer support through your app and on your web-site.
