🧠 Sequence Memory

How to play

A random number is shown in large digits for a couple of seconds, then replaced by question marks. Type it back exactly and you move up a level, where the next number is one digit longer. Get it wrong and the run ends, with the correct number shown so you can see how close you were.

• Start button — begins a run at level 1 with a four digit number. After a mistake it returns as Try Again and restarts from level 1.
• Answer field — type the digits here. It is locked while the number is showing and unlocks, already focused, once it is hidden.
• Enter key — submits your answer.
• Tick button — beside the field, does the same as Enter.

Scoring

There are no points, only levels. Level 1 shows a four digit number and every level adds one digit, so level 5 is eight digits. The display time also grows, starting at 1.7 seconds and gaining 0.2 seconds per level, but the extra digit costs more than the extra time gives back. Best records the highest number of levels cleared in one run and survives until you reload. Answers are compared exactly, after trimming spaces at the ends.

Tips

• Chunk the digits. Reading 5271840 as 527-18-40 is far easier to hold than seven separate digits.
• Say the number under your breath while it is on screen — the sound lasts longer in memory than the sight.
• Start typing immediately. There is no timer on your answer, but the longer you wait the more it fades.
• If you only half remember, type what you have. The run ends either way, and you learn where your limit is.
