Shape sequence memory
Remember the shape order together, from 3 steps to 8.
How to use
2–6 people share one device, watch a sequence made from four fixed shapes, then discuss and recreate the original order. Start with 3 steps and add one after each correct round. Complete 8 steps together, with no timer or sign-in.
Start in three steps
- Watch the complete sequence together first. Each of the four shapes has a fixed number from 1 to 4, and shapes may repeat. Input stays locked during playback, with a clear gap even between identical shapes.
- After the sequence is hidden, select the shapes from memory. The answer must exactly match the round length before submission. You can undo the last step, and cannot add more after filling every slot.
- A correct answer keeps the original sequence, adds just one step, and replays from the start. Completing 8 steps wins. A wrong answer reveals the correct sequence, the group's answer and the first mismatch, then ends the game.
Storage and limitations
The sequence, answer and longest successful length stay in page memory, without server upload or persistent storage. Leaving, refreshing or page eviction clears them. Backgrounding during playback interrupts it; on return, replay the same sequence from step 1. The tool never catches up automatically, changes the sequence or unlocks input.
Frequently asked questions
Can the same shape repeat in shape sequence memory?
Yes. Every step is independently selected from four fixed shapes, including adjacent repeats. Playback inserts a clear gap, while the numbers 1–4 and shape names stay fixed so recognition never relies on color alone.
Does a correct answer create an entirely new sequence?
No. After completing 3–7 steps, the full original sequence remains and only one step is appended before playback restarts at step 1. Completing 8 steps wins, and no ninth step is created.
What happens if I switch apps or tabs during playback?
Playback stops immediately and input remains locked. On return, select Replay this round to show the same sequence again from step 1. No unseen step is skipped, and the sequence is neither redrawn nor extended.
