Visible odds, strategic bets. Choose the likely color, size your bet, and manage your bankroll rationally.
Explicit probability gambling task. 10 colored boxes, visible ratio, hidden token. Choose a color and bet a fraction of your bank.
A final bank of 140+ indicates near-optimal probabilistic reasoning. Average is 90–115.
Rational bet-sizing — allocating more capital to higher-edge opportunities — is the foundation of all good investment strategy.
Understanding that past outcomes don't change future probabilities prevents the loss-chasing bias that destroys bankrolls and portfolios.
Calibrated probabilistic reasoning is the basis of Bayesian thinking — updating beliefs appropriately as new evidence arrives.
Gambit tests probabilistic reasoning— your ability to use explicit probability information to make optimal decisions. Unlike Inflate (which has hidden risk), Gambit shows you exactly the odds. Irrational play here isn't about missing information — it's about failing to act on the information you have.
The mathematically optimal bet size is given by the Kelly Criterion: bet a fraction of your bankroll equal to your edge. For a 70:30 advantage, edge = 0.7 - 0.3 = 0.4 → bet 40% of bankroll. Betting more than Kelly risks ruin; less than Kelly sacrifices growth. Most people bet too much on near-even odds and too little on strong advantages.
Color bias: Preferring red or blue independent of the odds. The boxes tell you the probability — trust the boxes.
Loss chasing: Betting more after a loss to "recover." Each round is independent — your previous outcome has zero predictive value.
The Gambit Test measures probabilistic reasoning and rational decision-making under known risk. Unlike real-world gambling where odds are hidden, this test shows you the exact probability distribution and tests whether you can use that information optimally to maximize your bankroll.
A grid of colored boxes shows the probability distribution (e.g., 7 red, 3 blue). Pick which color will be drawn, then bet a fraction of your bank (25%, 50%, 75%, or 90%). If correct, you gain the bet amount. If wrong, you lose it. Busting (reaching 0) resets your bank to 10. Duration: 80 seconds.
SENWITT converts raw performance into calibrated percentile results. We apply device input-latency calibration so that your score reflects cognitive and sensorimotor performance rather than hardware quirks. For tests with multiple attempts or levels, the score uses the test's built-in aggregation rule (for example, median/maximum/longest successful run), then maps that aggregated value against a global cohort to produce a percentile ranking.
The average final bank is about 105 points. Scores above 150 indicate excellent probabilistic reasoning. The optimal strategy is to always pick the majority color and bet large when the edge is highest (9:1 ratio) and small when it's low (5:5).
Probabilistic reasoning tasks reveal systematic biases in human decision-making documented by Kahneman & Tversky's prospect theory (1979). Most people overweight low-probability events and underweight high-probability ones. Optimal play in the Gambit involves always choosing the higher-probability color and sizing bets proportionally to your edge.
Always pick the more likely color — never bet against the odds.
Scale your bets to your edge — bet bigger on 9:1 ratios than 6:4 ratios.
Avoid the gambler's fallacy — each draw is independent; past results don't affect future outcomes.
Manage your bankroll — surviving is more important than one big win.
