在线桌上冰球：用手指或鼠标拖动击球器和电脑对打，把冰球撞进对方球门、守住自己的球门。冰球会在边框反弹，击球速度越快冰球飞得越快；电脑有简单、中等、困难三档，先拿到 5 或 7 分获胜。手机电脑都能玩，记录胜负场次。Air hockey online: drag your mallet with a finger or the mouse and face the computer — knock the puck into its goal and defend your own. The puck rebounds off the rails and flies faster the harder you hit it; the computer has easy, normal and hard levels, and the first to 5 or 7 wins. Works on phones and computers, with wins and losses tracked.

玩法说明与常见问题How to play & FAQ
「桌上冰球」怎么玩？How do I play Air Hockey?
你控制下方的蓝色击球器，电脑控制上方的红色击球器，双方都不能越过中线。用击球器撞击冰球，把它打进对方的球门（顶部红色开口）就得 1 分；冰球碰到边框会反弹，所以斜着打、借边反弹往往更难防。失分的一方获得下一次发球。击球时的移动速度会传给冰球，快速迎上去能打出大力射门。You control the blue mallet at the bottom and the computer controls the red one at the top; neither may cross the centre line. Strike the puck into the opponent's goal (the red opening at the top) to score; the puck bounces off the rails, so angled bank shots are harder to stop. Whoever concedes serves next. Your mallet's speed carries into the puck, so moving into it quickly makes a powerful shot.
电脑太难了怎么办？The computer is too strong — what can I do?
把难度调到「简单」，电脑的击球器会移动得更慢；也可以多利用边框反弹进球。Switch to Easy so its mallet moves more slowly, and try bank shots off the rails.
需要联网对战吗？Is it online multiplayer?
不需要，对手是本地运行的电脑程序，打开网页就能玩，离线也行。No — the opponent runs locally in your browser, so it even works offline once the page has loaded.
「桌上冰球」免费吗？需要下载吗？Is Air Hockey free? Do I need to download anything?
完全免费，无需注册、下载或安装，打开网页就能玩，手机、平板和电脑都支持；游戏完全在你的浏览器本地运行，不会上传任何数据。It is completely free with no sign-up, download or install — just open the page on a phone, tablet or computer. The game runs entirely in your browser and nothing is uploaded.
