ThinkPalette: Mind Workout

ThinkPalette brings together six training games themed around memory, focus, mental math, planning, probability, and magnitude. Choose a level and play condition, then repeat at your own pace. Choose a game on Home, set its level and options, and begin. Self-paced games wait for your answer and advance only when you choose Next. You can pause or end a session at any time. Key features - Digit Span: remember a sequence of digits and enter it in order - N-back: decide whether the current digit matches the one shown N steps earlier - Percentage: work with base amounts, compared amounts, rates, discounts, and increases or decreases using whole-number problems, with an optional scratch calculator during answering - Planning: remember a fictional plan, then consider sequence, priority, and changes as dates, times, and events appear - Probability: answer exact chances as fractions or percentages, count combinations, choose the most likely outcome, compare two strategies, and classify likelihood.
