Train by skill · Logic
Read the evidence, separate the moving parts and find the one rule that keeps every step consistent.
Predictionoutline circle
Generated visual reasoning
Inspect five steps, work out how the features change and choose the only continuation produced by the same rule.
Solver-verified deduction
Place zeros and ones so every row and column stays balanced, avoids triples and remains different from every other line.
Logic puzzle formats
Logic is not one mechanic. Some puzzles ask for a continuation, others for a unique arrangement or a contradiction-free explanation. What they share is a conclusion that follows from the information given.
Track changes in shape, mark, count or direction, then identify the next step that satisfies every active pattern.
Combine clues to rule out impossible pairings until each person, place or object has one consistent match.
Fill a board while obeying several simultaneous rules, as in Sudoku, Futoshiki, Binairo and similar logic games.
Test statements against one another to discover which combination can be true without creating a contradiction.
Apply moves, rotations or ordering rules to reach a goal while respecting the limits imposed by the puzzle.
A good logic puzzle gives you enough information to reach a defensible answer. The challenge is not remembering a hidden clue or spotting an item quickly; it is discovering how the visible facts fit together.
A logic puzzle establishes facts, relationships or constraints and asks you to infer something that has not been stated directly. Every useful clue narrows the possibilities. The intended answer should satisfy all the information at once, not just resemble part of it.
Pattern Sequence asks you to infer a changing visual rule. Binary Grid states all three rules in advance, then asks you to propagate their consequences across a complete board. One is prediction; the other is constraint-based deduction.
That distinguishes logic from the neighbouring workout skills. A memory game removes information before asking for it back. An attention game keeps the target visible but surrounds it with distractions. A logic game can leave everything on screen because the work lies in combining it correctly.
Prefer the simplest rule that accounts for every step. If an idea only explains the latest change, keep testing.
Given only a few terms, it is always possible to invent an elaborate mathematical or visual rule that produces a different next answer. That does not make every continuation equally useful. Well-made puzzles establish a clear visual vocabulary and favour a compact, consistent operation over a contrived exception.
Pattern Sequence works from nine named rule families rather than selecting arbitrary pictures and hoping a pattern appears. The generator builds the sequence from its intended rule, creates alternatives that break a specific feature and validates the resulting question before it is shown.
An introductory sequence may hold the shape still while an internal mark alternates. More demanding questions can run two processes together: perhaps shapes follow a three-item cycle while marks follow a two-item cycle. Neither track is difficult alone, but their periods meet at different points.
Difficulty can also come from the kind of change. A fixed quarter-turn is easier to describe than two opposed rotations, while a growing count requires comparing amounts rather than simply matching icons. Hard mode uses denser combinations without relying on microscopic details.
Accuracy contributes 88% of the base score and speed contributes 12%. This balance rewards solving the rule correctly while still recognising an efficient solution. The speed contribution is suppressed near chance performance, so rapid guessing is not a shortcut to a strong score.
Easy, Standard and Hard results are kept separately because they use different question counts, time limits and rule mixes. The score is a recreational workout result for personal comparison, not an intelligence test or a measure of neurological health.
Completing the one valid board contributes 75% of its score. Control contributes 20% and is reduced by failed checks and resets. Pace contributes only 5%, keeping careful deduction far more valuable than rapid entry. An unfinished grid receives limited cell-progress credit but no completion or pace credit.
Pattern Sequence belongs to the eight-skill Daily Workout rotation. Five distinct skills are selected for each local date, so Logic appears on five days in every balanced eight-day cycle and can occupy any station position. When selected, everyone receives the same Standard questions.
Binary Grid is standalone-only while its Standard duration and scoring are evaluated for future Daily eligibility. You can practise Easy, Standard or Hard without replacing the first completed result from today’s full workout.
Yes. Pattern Sequence, Binary Grid and the full Daily Brain Workout can be played without an account, registration or payment.
Yes. Pattern Sequence draws from nine authored rule families. Binary Grid builds a valid solution and removes clues only while an exact solver proves uniqueness.
Pattern Sequence identifies the intended rule after each choice. Binary Grid marks cells involved in a balance, triple or duplicate-line conflict without revealing the hidden solution.
Yes. Both games provide complete keyboard controls. Binary Grid adds arrow-key navigation plus direct 0, 1 and Delete entry.
No. It records one recreational attempt under a particular rule set and time limit. It is not an intelligence, educational or medical assessment.
