This is a submission for the Alibaba Cloud Challenge: Build a Web Game.*

What I Built

Here's another game I've made, and it's a simpler one.

This is a classic memory game where a robot shuffles your cards. Each card features the name of an Alibaba Cloud service, such as

ECS,
Function Compute
OSS
EBS
CDN
ApsaraDB

Your goal is to find matching pairs by clicking to flip the cards.
Cards will automatically flip back after one second. If you flip more than two cards within that second — even if you found a matching pair
— the move is considered invalid. When you successfully match two cards, they will remain face-up and become unclickable. Once you match all the pairs, your completion time will be recorded, and you can enter your name to appear on the top score board. The faster your time, the higher your ranking.

Enjoy!

Alibaba Cloud Services Implementation

After registering to Alibaba Cloud using the provided link, I unfortunately did not receive the free trial credit, even though this was my first time trying Alibaba Cloud. Despite this, I decided to purchase the necessary services myself, and, due to budget considerations, I opted for a simple and low-cost setup.
