Hit Telegram-based crypto game Hamster Kombat continues to expand ahead of its planned airdrop on The Open Network, and the latest addition is a daily puzzle mini game and the mysterious keys tied to it.

Added on July 19, the puzzle mini game refreshes daily and challenges you to move red and green candlestick indicators—like those seen on crypto price charts—to claim a key before time runs out. And the keys could prove to be valuable or useful indeed.

As millions more players flood into Hamster Kombat and the promised airdrop draws nearer, serious players are surely looking for ways to make the most of the game and ensure they maximize their token haul. Here’s a look at how the daily puzzle works and what we know about the keys so far.

What is the puzzle mini game?

Hamster Kombat’s puzzle mini game is a riff on the classic sliding puzzle concept, in which you’re trying to move an object within a small, constrained space, and that can only be accomplished by moving the other slides in a certain order.

In this case, Hamster Kombat cleverly plays on its crypto premise by repurposing vertical and horizontal candlestick indicators to clutter up each daily puzzle, and making you solve the puzzle to slide a golden key through the exit. And you only have 30 seconds to do so.

It’s tough! The first couple puzzles have already been challenging, in part because of apparent control issues. Hamster Kombat says to update your Telegram mobile app if you’re having trouble. Also note that the red vertical indicators only go up and down, while the green horizontal indicators can only go left and right, which makes the puzzles even trickier.

And if you don’t solve the puzzle, then you’ll have to wait 90 minutes to try again. And much like the game’s daily combo and daily cipher, the puzzle mini-game is updated daily—in this case, at 4pm ET each day.

Luckily, because of the immense popularity of Hamster Kombat, there’s already a wealth of influencers and content creators that are whipping up videos showing successful solutions to each puzzle. So if you keep failing, just fire up Twitter or YouTube to find a video walkthrough and see if that helps—like the example below.

What are the keys for?

Keys are a brand new concept in Hamster Kombat, offering players something other than just in-game coins to accumulate. Currently, there’s no functional purpose for them—but the developers are clearly teasing some real value here.

“The mystery key that you have probably already come across is an extremely useful thing that may come in handy in the future!” the team wrote in a Telegram update. “There are many more exciting things to come, stay tuned!”
