Optiver "Number Logic" — the exact 2026/27 test, free
A screen-for-screen replica of the real Number Logic module: 26 find-the-next-term sequences on a single 25:00 countdown, answered by clicking one of five cards — clicking commits and auto-advances, with BACK and SKIP chips so you can return and change answers until you save.
Free, in-browser, no signup — opens the full assessment on its own page, exactly like the real screen.
What the real test looks like
Each screen shows one sequence — integers, fractions, or mixed — and five candidate next terms. Unlike Beat the Odds, the clock is shared across all 26 questions (25 minutes), clicking an answer card commits it and moves you forward, and you may navigate BACK to revisit anything before the final “SAVE AND SUBMIT”.
The recurring pattern families in the reported sets: repeating operation cycles (−1, +2, ×3, ÷4…), two interleaved sub-sequences, second-order recurrences like a(n) = 2·a(n−1) + a(n−2), product-of-previous-terms chains (including fractions), and difference ladders.
Scoring & strategy
+1 / −1 / 0 with candidate reports suggesting roughly 15 points is a safe bar. The shared clock changes strategy completely: bank every sequence you see instantly, SKIP anything that stalls you, and spend the final minutes returning via BACK to the skipped ones. One stubborn sequence can cost you five easy points elsewhere.

FAQ
What is the Optiver Number Logic test?
It is the sequence-puzzle module of Optiver’s online assessment: 26 find-the-next-term questions on one shared 25-minute countdown, five answer options each, scored +1/−1/0 with skipping allowed and back-navigation available until you submit.
What sequence patterns appear?
Reported sets lean on repeating operation cycles, interleaved sub-sequences, second-order recurrences, product chains (including fraction sequences), and difference ladders — usually ramping from integer warm-ups to fraction/recurrence hybrids.
How many points do I need?
Optiver doesn’t publish cutoffs; candidate reports across recent cycles suggest around 15 net points is competitive. Because wrong answers cost a point, accuracy beats coverage.
Is this practice test free?
Yes — all three full 26-question sets and the 2-question sample are free in the browser, no signup.
