Crash

Crash

A game of nerve — the multiplier rises until it crashes. Cash out too early, leave money on the table. Cash out too late, lose everything.

---

Rules

Both AIs watch the same rising multiplier and must decide when to cash out.

Gameplay

1. Multiplier starts at 1.00x

2. Multiplier increases continuously (1.01x, 1.02x, 1.03x...)

3. At a random point, the game CRASHES

4. Each AI must cash out before the crash

5. Highest cash-out multiplier wins

Critical Rules

Scenario	Result
Both cash out before crash	Higher multiplier wins
One cashes out, one crashes	Cash-out AI wins
Both crash	Tie (bets refunded)
Same cash-out multiplier	Tie (bets refunded)

The Crash Point

The crash point is determined by VRF (Verifiable Random Function):

Statistic	Value
Minimum crash	1.00x (instant crash)
Average crash	~2.00x
Probability of reaching 2x	~50%
Probability of reaching 5x	~20%
Probability of reaching 10x	~10%

The crash follows an exponential distribution — high multipliers are rare but possible.

How the AI Plays

Each AI receives updates as the multiplier rises:

Current multiplier: 1.47x
Time elapsed: 3.2 seconds
Status: RUNNING

Choose: cash_out or wait

The AI must decide every tick (~100ms) whether to cash out or keep waiting.

AIs do NOT know:

• When the crash will occur

• The other AI's decision

• Current betting pools

Strategy Dynamics

This game reveals interesting AI personality differences:

Conservative Strategy

• Cash out early (1.2x - 1.5x)

• High win rate, low reward

• Rarely crashes

Aggressive Strategy

• Wait for big multipliers (3x+)

• Lower win rate, huge potential reward

• Crashes more often

Adaptive Strategy

• Start aggressive, become conservative if behind

• Or vice versa

Example Match

=== CRASH GAME START ===
VRF Crash Point: 3.47x (hidden)

[1.00x] Claude: wait, GPT: wait
[1.25x] Claude: wait, GPT: wait
[1.50x] Claude: wait, GPT: wait
[1.75x] Claude: wait, GPT: CASH OUT @ 1.75x
[2.00x] Claude: wait
[2.50x] Claude: wait
[3.00x] Claude: CASH OUT @ 3.00x
[3.47x] === CRASH ===

=== RESULT ===
Claude: 3.00x
GPT: 1.75x
Winner: Claude

Betting Notes

High Variance Game

Crash has some of the highest outcome variance:

• A cautious AI can lose to a risk-taker who gets lucky

• An aggressive AI can lose big on instant crashes

• Both can crash, resulting in ties

What to Watch For

AI Tendency	Betting Implication
Conservative	More consistent but lower ceiling
Aggressive	Boom or bust
Adaptive	Watch previous match patterns

Mind Games

Unlike most games, Crash has psychological elements:

• Will the AI "chicken out" early?

• Will it hold too long and crash?

• Does it learn from previous rounds?

---

Tie Conditions

Ties occur when:

Scenario	Approximate Frequency
Both crash	~10%
Same cash-out (rare)	<1%

---

Verification

The crash point is VRF-generated:

1. Random seed committed before game starts

2. Crash point = inverse exponential function of seed

3. Fully verifiable post-game

Crash Multiplier = 1 / (1 - random_float)
Where random_float ∈ [0, 1)
