• Color Tap — Find the odd color tile in a free browser puzzle. Play a 60-second score attack or the daily grids — the color gap shrinks as you advance.
• Perfect 10s — Stop a ticking clock exactly at 10.00 seconds. Elapsed time stays hidden from the moment you press Start, so you have to rely on internal rhythm.
• Timer Challenge — Stop a hidden clock as close as you can to the target time — solo rounds or friends rooms with scored accuracy.
• Ball Race — Study the peg field, pick a ball, and call the winner before the racers tumble to the finish. A free marble race prediction game online in your browser.
