I am doing a internet cafe sweepstakes slot game in vb.net. I want to show the objects based on the payout and the prize money for paylines in the slot game. I tried using MT algorithem but it basically random number based. the final output should not be radom.

Inputs

  1. Points Ex. 18 or 50 (2 entries) 9 or 25 (1 Entry)
  2. prize (from database) Ex. 200 cents
  3. Total Lines Ex. 9 or 25
  4. 1 Line = Points/Lines (18/9) = 2 Points
  5. Reels = 5
  6. Rows = 3
  7. Pay Table\Pay out = 10 Arrays Ex. obj1(0) = 0, obj1(1) = 20,obj1(2) = 100,obj1(3) = 300,obj1(4) = 2000,
  8. Line array Example: L1 (2,1)(2,2),(2,3),(2,4),(2,5) = 2 Points = 15 cents L2 (1,1 )(1,2),(1,3),(1,4),(1,5) = 2 Points = 300 cents L3 (3,1)(3,2),(3,3),(3,4),(3,5) = 2 Points = 30 cents L4 (1,1)(2,2),(3,3),(2,4),(1,5) = 2 Points = 200 cents L5 (3,1)(2,2),(1,3),(2,4),(3,5) = 2 Points = 0 cents L6 (2,1)(3,2),(3,3),(3,4),(2,5) = 2 Points = 20 cents L7 (2,1)(1,2),(1,3),(1,4),(2,5) = 2 Points = 6 cents L8 (1,1)(2,2),(2,3),(2,4),(1,5) = 2 Points = 0 cents L9 (3,1)(2,2),(2,3),(2,4),(3,5) = 2 Points = 10 cents

Output

3 X 5 Matrix

I cannot understand this question but it looks an awful lot like homework. – BlueRaja - Danny Pflughoeft
@BlueRaja - Danny Pflughoeft so then should it get a homework tag? – rook

With any random number generator you have to seed its input. For random number on windows platform your best off just using CryptGenRandom(). Keep in mind that time() alone is a very bad seed because often times the attacker knows the time. 

  <DllImport("coredll.dll")> _
  Public Shared Function CryptGenRandom( _
     ByVal hProv As IntPtr, ByVal dwLen As Integer, _
     ByVal pbBuffer() As Byte) As Boolean
  End Function
