You pick heads or tails. A coin flips. If you're right, you win. If you're wrong, you lose. The simplest game in any casino.
A fair coin gives you exactly 50% odds on each side. In crypto Coinflip, the house edge is built into the payout. Instead of paying exactly 2x your bet on a win (which would be perfectly fair), the casino pays slightly less -- typically 1.96x or 1.98x. That tiny difference is how the casino makes money.
At SPUNK BET, Coinflip is provably fair. The result is determined by SHA-256 hashing before the coin animates. No manipulation is possible.
Let's break down the numbers. With a 1.98x payout and 50% win chance:
| Bets | Total Wagered | Expected Wins | Expected Return | Expected Profit/Loss |
|---|---|---|---|---|
| 10 | 1,000 SPUNK | 5 | 990 SPUNK | -10 SPUNK |
| 100 | 10,000 SPUNK | 50 | 9,900 SPUNK | -100 SPUNK |
| 1,000 | 100,000 SPUNK | 500 | 99,000 SPUNK | -1,000 SPUNK |
Over the long run, you'll lose about 1% of your total wagered amount. That's the house edge. But in the short run -- over 10, 20, or even 50 bets -- anything can happen. You might win 7 out of 10 flips. Or lose 8 out of 10. Short-term randomness is where the excitement lives.
The simplest and safest strategy: bet the same amount every single flip.
Pick a bet size (100 SPUNK). Bet that amount on every flip. Never change it based on wins or losses. Set a stop-loss and win goal before you start.
Flat betting gives you the most predictable experience. Your balance will random-walk up and down around your starting point, slowly drifting down due to the house edge. But individual sessions can absolutely end in profit.
Recommended settings:
The Martingale system is the most famous betting strategy ever. Double your bet after every loss. When you finally win, you recover all previous losses plus one unit of profit.
On paper, it sounds perfect for Coinflip. In practice, it's a trap.
| Flip # | Bet | Result | Total Loss |
|---|---|---|---|
| 1 | 100 | Lose | -100 |
| 2 | 200 | Lose | -300 |
| 3 | 400 | Lose | -700 |
| 4 | 800 | Lose | -1,500 |
| 5 | 1,600 | Lose | -3,100 |
| 6 | 3,200 | Lose | -6,300 |
| 7 | 6,400 | WIN | +100 (net profit) |
After 6 losses and 1 win, you risked 12,700 SPUNK to profit just 100. And losing 6 in a row happens roughly 1.5% of the time -- about once every 64 sessions. When it happens (and it will), you're wiped out.
Verdict: Martingale produces many small wins and rare catastrophic losses. The expected value is the same as flat betting (slightly negative due to house edge). The only thing Martingale changes is the distribution of outcomes, not the math.

The opposite of Martingale: double your bet after every WIN, reset after a loss.
Start with 100 SPUNK. Win? Bet 200. Win again? Bet 400. Lose? Back to 100. You're riding winning streaks and cutting losses short.
Anti-Martingale produces many small losses and occasional big wins. It feels better psychologically because you're only risking "house money" when you increase your bet. But mathematically, it has the same expected value as flat betting.
The key decision: how many wins before you reset? Most players use 3-4 consecutive wins as their cap. After 3 wins starting at 100 (100 → 200 → 400), cash out the 400 and restart at 100.

Claim Your Free SPUNKYou'll see streaks in Coinflip. Five heads in a row. Seven tails in a row. It feels wrong. It feels like the game is rigged. It's not. Streaks are a natural, expected part of random sequences.
In 100 coin flips, you should expect at least one streak of 6-7 in a row. That's just math. A 50% chance repeated many times produces clumpy results, not perfectly alternating outcomes.
The gambler's fallacy: "I've lost 5 in a row, so the next one must be heads." Wrong. Each flip is 50/50 regardless of what happened before. The coin has no memory.
Knowing this protects you from emotional decisions. When you see a streak, don't increase your bets trying to "catch the reversal." There is no reversal. There's just the next independent flip.
The coin itself is 50/50. The payout includes a small house edge (typically 1-2%), so you get 1.96-1.98x on wins instead of 2x. The flip is fair; the payout is slightly in the casino's favor.
Short-term, it produces consistent small wins. Long-term, the inevitable long losing streak wipes you out. It doesn't change the expected value. Test it with free SPUNK tokens first.
At SPUNK BET, yes. Every flip is determined by SHA-256 hashing before the animation plays. You can verify each result independently.
Flat betting at 1% of your balance. No fancy systems. Set a stop-loss, set a win goal, play 50 flips, and walk away. Simple and effective.
It doesn't matter. Heads and tails have equal probability on every flip. Picking the same side, alternating, or choosing randomly all produce the same long-term results.
