## Description

See the expected value behind every hit, stand, double, and split. The blackjack basic-strategy trainer that shows its work — educational, ad-free, beautifully built.

Double Down is the blackjack trainer that shows its work.

Most apps just tell you the "correct" move. Double Down teaches you the math behind it — the expected value (EV) of every decision — so you stop memorizing a chart and start genuinely understanding the game.

No Double Down account required; optional iCloud sync and Game Center achievements use your Apple account.

HOW IT WORKS
• Deal a real hand and choose your play — hit, stand, double, split, or surrender.
• Get instant feedback on whether it was the EV-optimal decision.
• Tap to see exactly why.

SEE THE MATH
Every hand opens into a clear, honest breakdown:
• Expected value of each action, side by side
• Win / push / loss probabilities
• Your bust risk if you hit
• The dealer's full distribution of final totals

TRAIN FOR YOUR EXACT TABLE
Basic strategy changes with the rules — so configure them all:
• 1–8 decks
• Dealer hits or stands on soft 17 (H17 / S17)
• 3:2 vs 6:5 blackjack payouts
• Late, early, or no surrender
• Double after split, resplits, hit split aces
• Even the Free Bet variant

TRACK YOUR PROGRESS
• Accuracy, streaks, and decisions over time
• Performance broken down by situation
• Your recent mistakes, so you always know what to drill next

LEARN THE CONCEPTS
Ten focused lessons on the probability and expected value beneath basic strategy — hard totals, soft totals, pairs, doubling, surrender, and how each rule change moves the math.

DESIGNED TO FOCUS
A quiet, premium, ad-free experience with a beautiful Day and Night theme. Practice works locally; optional iCloud sync and Game Center achievements use Apple's services when enabled.

Double Down is an educational strategy trainer: no real money is staked and no wagers are placed.
