Guess — free browser game

Your goal is to work out the pattern hidden in the top row and figure out what the final box, shown with a question mark (?), should be. Each round, four boxes carry a piece of logic: a number sequence (e.g. 2, 4, 6, 8 → ?), an alternating arrangement of two or three colours (red, blue, red, blue → ?), a shape rotation (triangle at 0°, 90°, 180°, 270° → ?), or a combo pattern where number and colour change together. The heading at the top tells you which type of pattern it is. Choose the correct continuation from the four options below by clicking with the mouse or pressing the 1-4 keys; a correct answer raises your score by +1, while a wrong choice or letting the 12-second timer run out costs you a life. When all three lives are gone the game ends and your best score is saved; the R key or the Restart button starts a new game. Tip: first look at the heading label to narrow down the pattern type, then focus on the difference between two consecutive boxes (the step in numbers, the order of colours, the direction of rotation in shapes) — don't rush, but make your decision before the time bar turns red.
