Complete Bet

Every inside bet that includes one number, each sized so that a winning part pays the same.

Short answer

A complete on 17 is 40 chips: the straight up, four splits, the street, four corners and two six lines. If 17 comes up every chip wins and the bet makes 392 chips; nine pockets in 37 win something. The price is still 2.70%.

Why the parts are sized that way

A bet on n numbers pays 36/n − 1 to 1, so a winning chip on it comes back with 36/n chips, stake included. Put n chips on it and a win always returns 36 chips, whatever kind of bet it is. That makes a complete quick to settle: count the parts that won and multiply by 36. When 17 comes up all twelve parts win: 12 × 36 = 432 chips back for the 40 staked, a profit of 392.

Bets with the zero (the splits 0/1, 0/2 and 0/3, the three-number bets 0-1-2 and 0-2-3 and the first four, 0-1-2-3) are counted, as in Resorts World’s drawing of a complete on 0, which comes to 17 units. Figures are ours.

The maximum

A complete at the table’s limit is called a maximum: “17 to the maximum”. Resorts World’s rules define it as a complete whose unit is the table’s maximum unit. If that unit is $1,000, the bet is $40,000 and makes $392,000 when 17 comes up. It is the high roller’s bet because it is the most a table lets anyone put behind one number, and it costs what every other bet costs: on average $1,081 a spin.

A hit pays +116 on the four corner numbers of the dozen, +188 on the top and bottom numbers of its middle column, +224 on the outer numbers of its two middle rows and +332 on the two numbers at its center; the other 25 pocketsequipmentPocketOne of the 37 numbered compartments on the rotor.

Questions

Is a complete a good bet?

It costs 2.70% like every bet on a single-zero layout. It puts the stake around one number: nine pockets in 37 win something, and most of the money comes from one of them.

Can I play one at an American table?

You can place the same chips yourself if the dealer will not build it. On a double-zero wheel every part costs 5.26%.

Why “complete”?

It completes the number: every inside bet that includes it is on the table.

Comic relief

Twelve bets, one number, the same 2.70%.
