Six Seven: Count Fast

The pitch

Six or seven? A pile of apples, stars, coins or hearts flashes for about a second, and the flashes get shorter with every right answer. Count it by eye and answer 6 or 7 before time runs out. The piles get trickier as your streak grows: mixed sizes, overlapping heaps, drifting piles and decoy items that don't count. Reach a streak of 67 to face the final boss: 67 items laid out as a giant 67. Dress up your character in the shop with 75 cool and funny items, from shades and chains to a traffic cone and a dino suit. Beat your best streak and climb the leaderboard.

Controls & how it runs

Look at the pile while it is shown and decide whether there are 6 or 7 items, then answer before the timer bar runs out. On a phone tap the left half of the screen for 6 or the right half for 7. On a computer press Left Arrow, A or 6 for six and Right Arrow, D or 7 for seven, or click the buttons. Items of a different color and shape are decoys and do not count. One wrong answer ends the run. At streak 67 the final boss asks how many items you saw: pick with the buttons or keys 1 to 4. P or Esc pauses, M toggles sound.

Getting a run going takes exactly one press: Press start, up top, and the game boots inside this page — nothing downloads in the background and no form wants your details before the first jump. The cabinet is drawn for a flexible screen and listens to mouse, keyboard or touch, whichever the game prefers. It reshapes itself for tall and wide screens alike, so phone, tablet and desktop all get the full picture. Given a fullscreen button, use it — scores look better at full size, that's just science.

Pro tips for puzzle cabinets

• Count what's missing, not what's there. In matching and logic boards the empty spaces and absent pieces usually draw the shape of the solution for you.
• Solve the corner first. Constrained edges and locked pieces have the fewest options, which makes them the honest starting point of almost every board here.
• If you're stuck, change the order, not the plan. Many boards on this row are the same moves played in a different sequence — the lock was the order all along.
