Random Addingby Melirate

Solo play

Play a solo round

Set up a timed addition sprint as a guest, or practice for an explicitly selected Melirate learner when member access is enabled.

Available locallyJourney guide

Before you start

  • Guest play is available immediately; first guest play asks for a nickname. Member practice requires an enabled identity service. The current hosted preview is still unconfigured for member access.

Steps

  1. Check the round settings

    The starting round uses two addends capped at 10, no maximum total, and 60 seconds. Edit these first if you want a different round.

    Open the Setup: the default round guide

  2. Choose guest or member practice

    Choose Play now for guest play; first use asks for a nickname and starts without an account request. To use a Melirate learner, explicitly choose Sign in. In a configured build, Home handles sign-in and asks you to choose a learner before Continue. Random Adding then opens member setup for the verified selection. This does not change an active guest or group round.

  3. Answer each problem

    Enter digits with the keypad or keyboard and submit with the arrow or Enter. A correct answer earns one point and moves to the next problem; a wrong answer is recorded as incorrect, earns no point, resets the streak, and moves immediately to the next problem. Member questions and scoring run locally, so answers do not wait for a network request.

  4. Finish and choose what is next

    The timer continues if the tab is in the background. At zero, results appear before member sync finishes. Member results show Saving, Saved, Retry, or another truthful sync state; only a confirmed canonical receipt says Saved, and saved answers link to Activity. Choose Play again for another round or Change settings to return to setup while sync continues.

What to expect

  • Guest play begins without an account request or per-question network wait; there is no pause control.
  • Member play begins locally and never waits for per-question sync. Only verified self practice can sync canonically; guest and member data remain separate, and eligible solo answers count toward skill predictions.
  • The recording and screenshots show an earlier guest build. Its wrong-answer retry segment is archival: the current game advances after every valid answer. They do not depict the locally prepared member screens.

Recorded walkthrough

Walkthrough recording · 22 sec

These are silent local synthetic preview captures. Account clips and screenshots show the unconfigured guest preview, not the locally prepared member flow. Some demos use 5-, 15-, or 20-second timers; private invitation details are hidden. If playback is unavailable, use the captions when present or read the full transcript below.

The setup starts at one minute. For this synthetic demo, use the seconds wheel to shorten the round.

This recording uses a 15-second timer so the result appears quickly.

On first use, enter a nickname for this device-local guest profile.

The timed round starts at the first question. The answer field and number keypad both accept a response.

Earlier version shown: current wrong answers are recorded as incorrect and advance immediately.

A correct answer increments the score and advances to a new problem.

When the timer ends, the app shows the score and round summary. The short timer is only for this demo.
