Description

About Doubles Hard PC Steam CD Key

Doubles Hard is a game inspired by a legendary production Boulder Dash, created by Peter Liepa and released by First Star Software in 1984. Unlike the original Doubles Hard game, diamonds are collected on a three-dimensional board. The player can move up, down, left, right, in and out. There is also 'grab' move. The use of the three-dimensional board has made it possible to design completely new levels that put the game on an even higher complexity level. The two-dimensional version of Boulder Dash has been implemented in a huge number of ways and enjoyed well-deserved popularity. Adding a third dimension increases the level of difficulty, but also the satisfaction of gameplay. Features of the gameplay: 45 levels (and one extra) All classic blocks available (diamonds, boulders, grass, lava, enemies, walls) A new kind of block: the bomb! Keyboard and pad support. The first game referring to Boulder Dash, played on a three-dimensional board! If you try, there will be chaos on the screen. But this chaos is under control. Under Your control!

Are all of your products legit?

How fast will I receive my order?

Most orders are delivered instantly after purchase. Some account-based products may take up to 24 hours for manual processing; but we always aim to get it to you as fast as possible. You’ll see the expected delivery time clearly on each product page.

Is anything sent to my address?

Never. All of our products are digital, that means, whether it's a code, an account, or a subscription, everything is delivered online. No physical shipping, no delays, no postage fees.

How do I redeem/see my order?

After purchase, you'll receive a secure link to view your key or account details. If the product requires manual processing, we’ll send a redemption link as soon as it’s ready. Step-by-step instructions are included whenever needed. (You may always view your order details on your dashboard if you created an account).
