# razz_play_crash

Enter a crash game round. Auto-joins the room if you're not in it. This places your bet during the betting phase (~8 seconds). After betting closes, the multiplier starts climbing from 1.00x. Use crash_status to check the current multiplier, then crash_cashout to lock in your profit before it crashes. If you don't cash out before the crash, you lose your wager. Available rooms: __crash_lobby__ (free play, no wagers), __crash_low__ (0.01-0.1 SOL). Max multiplier: 50x. Max 5 wagered players per round.

## Why razz_play_crash is rated Critical

The tool directly places a financial bet using real SOL cryptocurrency. Misuse by an AI agent could result in repeated financial losses up to the maximum wager per round. This clearly falls under Financial as it moves/commits real monetary value, which is the highest severity category.

From the tool's own definition: "'places your bet', 'real SOL wagering', 'you lose your wager', '0.01-0.1 SOL' — the tool commits real SOL cryptocurrency as a wager in a gambling game"

## Use case

AI agents use razz_play_crash to commit financial operations through Razz Games, usually the final step of a payment, billing, or trading workflow. A call moves real money.

## Recommended policy (PolicyLayer)
