TOMMYBOYS
A 1930s street corner. The crew empties a Thompson into the car and the spent shell drops through twelve rows of pegs. Land wide for the big money, or fall into the dead middle.
One Curve. One Decision.
Tommy Boys is a Plinko on the same committed-seed core as the other titles. One press drops one shell through twelve rows of pegs into thirteen slots, three risk levels reshape the paytable without touching the return, and any shell can put the car up for a twelve-sack pick. RTP is exactly 97% at every risk level and every stake.
A stake, a risk, one button
Set what a shot costs and pick EASY, HARD or EXTREME. All three return exactly 97%: the risk level changes the shape of the paytable, never its value. The strip above the button is the one you are shooting at.
The fall is the draw
The shell goes left or right at every peg with an even chance, and the slot it reaches is the number of rights. What you watch is the drawn result on its way down, not an animation fitted to an answer picked somewhere else.
One in 480, and never nearer
Any shell can destroy the car and open twelve sacks, three of them yours. The trigger is memoryless: it never builds up, and a car shot at all evening is no closer to going than one you have just started on.
The table is set
Stake, risk and the slot strip sit under the board, and the rail on the left keeps every shot you have taken this session.
The crew opens up
Press once and the Thompsons fire on the car. The spent shell is what falls, so the shot and the draw are the same event.
Left or right, evenly
The shell takes twelve independent decisions on the way down. Where it lands is the count of the rights, and nothing steers it.
Same return, three shapes
EXTREME thins the middle to 0.1x and pushes the ends to 555x. EASY pays small and often. The return is 97% on all three.
One shell in 480
Any shot can put the car up. The chance never builds, and nothing on screen suggests the car is close, because nothing is.
Twelve sacks, three picks
The sacks are shuffled before the screen opens, so every one is worth the same before it is opened. The rest are shown at the end.
Check The Math Yourself.
Every round is committed before it opens and verifiable after it ends. Operators do not have to take our word for it, and neither do their players.
COMMIT
Before a round opens, the server publishes sha256(server_seed). That hash pins the crash point in place before the first bet is taken.
PLAY
The round runs. crash_at derives from HMAC-SHA256(server_seed, client_seed:nonce), so neither side can steer the outcome mid-round.
REVEAL
After the bust, the server reveals server_seed. Anyone can rehash it, recompute crash_at, and confirm both match the record.
