The title may be outrageously wrong, but we all love Tetris and this is a rather good little UWP adaptation. True, the game speed stays the same as your initial setting rather than speeding up, but set the difficulty right for you and it'll be an excellent challenge. Jaunty music and attractive presentation help, though shame about the banner ads (and no way to pay to get rid of them)...

From the Store description:

Block Puzzle Tetris - Classic Brick keeps the original taste of brick block puzzle game known as the world-famous Tetris. Simple to play, but hard to master. Just swipe the blocks to form horizontal lines without gaps. Remember: Do not let the brick blocks touch the top of the frame.

■ Classic mode--16 difficulty levels

• Create the perfect strategy and keep your lines clear with endless Tetrimino action.
• The game ends if there is no space left for a new TETROMINO to place.

■ Challenge mode

• Clear the grey bricks in the bottom within the limited time.

Here's the game in action:

'Challenge' mode is where you get started with some semi-random blocks and have to clear the bottom row in order to proceed to the next set of blocks, etc. But most people will be happiest with 'classic' Tetris, as shown here. Pro tip: start on about level '7' for a good game - '1' is way too easy and slow!!
