Gridlock
Gridlock is an 8×8 block puzzle where your study questions deal the blocks. Answer right and you draw three; answer wrong and you get another question, so you only keep playing once you get one right.
The demo needs no account and no card.

About Gridlock
Drag each block onto the grid — they never rotate, so where you put them matters. Fill a full row or column to clear it, and clear on back-to-back turns to build a combo worth up to five times the points. Empty the whole board for a bonus.
Place the whole hand to earn the next question. When nothing in your hand fits, you get one rescue question: answer right and the two fullest rows and columns blast away; miss and the run ends with everything you answered saved to your results.

Why Gridlock helps you study
Every question directly sets how much room you have to work with, so a right answer is the only way to keep playing — the kind of stakes that make you actually think before you tap. Each hand is short, which keeps questions coming every minute or so.
