Unblock It 3D is a block-puzzle game in which the player directs floating stacks of short and long blocks marked with arrows to slide in different directions off the playfield. The game offers two fun modes (Classic and Journey).
With Classic, the player earns coins by removing all the blocks from fields across levels. If they decide to view an ad, they earn more coins based on a lucky rainbow bar multiplier. They must complete Level 3 to unlock the Journey mode. With Journey, they traverse a map that displays imitations of famous geographic locations and landmarks. They use buttons on the map to access each level. Their goal is to earn up to three gold stars per level. Both Classic and Journey modes eventually provide the player with a gift every time they reach a specific milestone.
The player starts with wooden blocks marked with arrows. Over time, they can use their coins to change the appearance of the blocks to add other wood patterns, stone and marble patterns, and even solid-colored plastic options. They also use their coins to change the field backdrop.�
Unblock It 3D offers boosters to enhance play. The player uses double arrows to make a block flip its direction, a bomb to blast away three random blocks, and a lightbulb to provide a green highlighted hint. They receive two free for each type, and then they must view ads for more.
