Drop Stack
Ten rounds. Tap the column with the lowest stack.
Why Drop Stack is in Kefiw Daily
What it trains
Drop Stack trains fast visual measurement: comparing stacks, spotting the lowest column, and resisting misleading shapes.
How scoring works
Correct answers score higher when made quickly. The useful habit is scanning the whole field before locking onto the first obvious option.
How to use it
Use it as a short eye-calibration drill before spatial work, layout decisions, or any task where visual comparison matters.
Privacy and review
Round state stays in local browser storage unless you choose to post a score. Use Kefiw Spatial after the round to review the underlying tool or practice family.
How to make the practice useful
Treat the score as a signal, not a judgment. A low score usually means the round exposed a specific skill gap: estimating too quickly, missing a constraint, losing track of a prior clue, or choosing the first plausible answer. After the timer ends, look back at one missed item and name the decision rule you would use next time. That short review is what turns a daily game into a cognitive-boost routine.
