Ultimate Block Puzzle is a free online puzzle game where your job is to fill outlined shapes by dragging and dropping differently shaped blocks into the correct positions. Each level gives you a target shape on screen, then feeds you a series of blocks one at a time through a panel below it. Your task is simple to understand but tricky to master: fit every block so the shape is completely filled with no gaps left over.

What makes this game genuinely challenging is that you can't just place blocks anywhere you want — each piece has to go inside the outline, and you need to think a few moves ahead. The blocks arrive in a fixed order, so rushing in without a plan will leave you stuck with an awkward shape that won't fit. Take your time, study what's coming, and figure out which sections of the outline to fill first. Successfully completing a shape rewards you with points, pushing you to keep improving your score.

This is a great pick for fans of block fitting games, shape puzzle games, and brain teasers online. Whether you're looking for a quick logic puzzle to play on a lunch break or a longer session of classic tile placement gameplay, Ultimate Block Puzzle delivers. It runs smoothly on both desktop and mobile browsers, making it a solid choice for anyone searching for free block puzzle games online, no download puzzle games, or fun skill-based brain games for all ages.
