Congratulations
The roulette-system Challenge 2.1
puts You way ahead of the average roulette Player
Beside even money bets, twelve number bets have always been
system players favorites.

The roulette strategy Challenge 2.1 fulfills the gain expectations of

real players, which are searching for a practicable
and at the same time gain active system.

The handling of the system is absolutely problem tree?

Conventional calculations of probability can t deal with twelve
number bets. A relevant cause for this is, that the distribution of
dozens and columns is very divergent on the roulette wheel,
the numbers are scattered, without a usable regulative factor In addition
a full bet is lost, when Zero or Double zero comes cut-
Therefore, with CHALLENGE 2 1 Cosmo-Research has developed an innovative
approach to attack dozens and / or columns,

Two strong components build this roulette strategy:

1. The basic betting pattern ensures an optimal hit rate.

2. The progression ensures that stagnation phases can lie overcome.

By integration of these two components. Challenge 21 achieves

net gain percentages, which seemed to be impossible so far.

This Explanation will familiarize you step by step with Challenge 2.1.

 INTRODUCTION

Challenge 2.1 adapts to the spin run and designates a bet on a dozen or a column
whenever a hit for this chance is most probable.
Following all demonstrations are executed on dozens, they apply equally also to
columns. The attack signal for Challenge 2.1 Is the appearance of all three dozens in
three consecutive spins'

This is our basic pattern to determine where to place our bets.

There are six possible appearances of this pattern;

We have now to place a bet on the first dozen.Spin 12 comes up
with No. 22. We lose our bet. On the next spin we bet again on the first dozen
Spin 13 comes up with No. 3. We win our bet.

Example No. 6 : 1999-08-20

Again with No's 31, 11 and 20 (spins 2, 3 and 4) we see our basic

out on spin 5. We lose our bet. On spin 6 we bet again the third
dozen. No. 6 comes out. We lose this bet also. We place a bet
on the third dozen the third time. On spin 7 No. 32 comes out,
We win this bet.
If a third bet In the betting sequence is lost we stop the game.
Now we have to waft for our basic pattern downstream of the

 INTRODUCTION

In spins 5, 6 and 7 we see our basic pattern.

Now we have to bet the third dozen.On spin 8 No. 24 comes out
We lose this bet Again we bet on the third dozen.Spin 9 is lost
also because No. 6 comes out.
We bet a third time on the third dozen and lose again due to
No. 20 on spin 10. We stop and continue to record the spins.

Spins 17,18 and 19 produce our basic pattern (No's 1,16

and 30).
For spin 20 we have to place a bet on the first dozen.
Spin 20 : No. 10, we win this bet.

We use this new pattern in spins 18, 19 and 20 (No's 16, 30 and 10)
to determine a new bet: we have to bet on the second dozen on spin 21.
Spin 21: No. 13, we win this bet too.

file:///C|/challenge2.1/Challenge21.htm (13 of 28) [12/3/2002 9:59:22 AM]

 INTRODUCTION

Now we use the pattern of spins 19, 20 and 21 (No's 30,10 and 13)
to determine a new bet on the third dozen on spin 22-
Spin 22 : No. 35, we win this bet

Spin 20, 21 and 22 form again our

basic pattern.
We have to bet on the first dozen on
spin 23.
Spin 23 : No. 4, we win this bet.
After the appearance of our basic pattern, we begin betting'
Whenever a first bet hits. a new basic pattern with the two previous spins.
is produced. We will use this pattern to determine a new bet and place that
bet on the very next spin !
Important: If a second or a third bet in a betting sequence hits. we have to
wait for a new basic pattern downstream of the hit-The spin of the last won bet
may be part of this new pattern
Example 09-29-1999: spins 21. 22 and 23 form the new pattern 'They are
downstream
from the last lost bet. We cannot use spins 19. 20 and 21 or Spins -20. 2l and 22!

Example 10-04-1999: spins 11. 12 and 13 form the new pattern They are
downstream from the last lost bet. We cannot use spins 9.10 and 11!

3. After three lost bets, we stop betting and wait for a new basic pattern downstream of

file:///C|/challenge2.1/Challenge21.htm (14 of 28) [12/3/2002 9:59:22 AM]

 INTRODUCTION

the last lost bet, before we continue with our game!

Example 1999-08-10 : obviously spins 37.38 and 39 form our basic pattern.
however we can not use these spins because, only spins 39 is downstream from
the last lost bet!

It s as simple as that'.

In the next section we will introduce you to our progression,

Challenge 2.1
The Progression

Systems which use equal size bets generally contain long lasting stagnation
phases, which make a strategic play uneconomic. expenditure of time and
yield are in no profitable relation to each other.

As alternative many systems offer a variety of progressions.

However, all progressions nave the disadvantage that with increasing bet sizes
the Zero-tax gradually grows also, until it is impossible for the progression
to regain the amount lost to Zero or Doublezero 1

Based on this realization Cosmo-Research has constructed a progression.

from now on called ..DIVISION", which goes a new, intelligent way.

The starting point of DIVISION is. that with a large probability within
a limited spin sequence there will be a certain number of hits.

file:///C|/challenge2.1/Challenge21.htm (15 of 28) [12/3/2002 9:59:22 AM]

 INTRODUCTION

When these hits will come is unpredictable, but that the hits will come
is probabilistically provable,

DIVISION uses 2 Code numbers, put into relation to each other.

From their variable relation the bet size is determined.

This type of bet size determination can be used profitably

on even money and on twelve number bets.

Now we are going to demonstrate how DIVISION works on

even money bets.assuming that the system ,X" will hit five times within
a specific sequence of consecutive roulette spins.

Gain target is 5 units:

win/loss Codel Code 2 division result bet balance

betl loss 5 5 5/5 1 -1 -1

bet 2 loss 6 5 6/5 1 -1 -2

bet 3 loss 7 5 7/5 1 -1 -3

bet 4 win 8 5 8/5 2 +2 -1

bet 5 win 6 4 6/4 2 +2 +1

bet 6 loss 4 3 4/3 1 -1 0

bet 7 win 5 3 5/3 2 +2 +2

bet 8 loss 3 2 2/3 2 -2 0

bet 9 win 5 2 612 3 +3 +3

bet 10 win 2 1 2/1 2 +2 +5

Although plus and minus are even, we have 5 hits and 5 failed hits.

file:///C|/challenge2.1/Challenge21.htm (16 of 28) [12/3/2002 9:59:22 AM]

 INTRODUCTION

DIVISION results with a 5 unit gain

How is this gain achieved?

The Code numbers of 5 were set against each other. Code 1 can be set
variable, it orients itself at the increase of bet sizes, up to which
you are willing to go The higher the Code 1, the more steeply the bet size
is increasing.
Code 2 corresponds to the number of hits. which you expect.
The two Code numbers are divided by each other. Results smaller man i
are rounded up to 1 unit. Results of the division greater than 1 -4 are
rounded up to 2 units, results between 2 and 2 4 are rounded down to 2,
from 2-5 rounded up to 3 and so forth.

Code 1 is increased after a loss by the number of the lost units. It is

reduced after a hit bv deduction of the amount of won units.
Code 2 remains unchanged after a loss and is reduced after a
hit by 1 pay out ratio of even money bets).

A further demonstration of DIVISION with the expectation of

a 10 unit gain after 10 hits follows:

win/toss Code l Code 2 division result bet balance

betl loss 10 10 10/10 1 -1 -1

bet 2 loss 11 10 11/10 1 -1 -2

bet 3 loss 12 10 12/10 1 -1 -3

bet4 win 13 10 13/10 1 +1 -2

bet5 win 12 9 12/9 1 +1 -1

bet6 loss 11 8 11/8 1 -1 -2

bet 7 loss 12 8 12/8 2 -2 -4

bet8 win 14 8 14/8 2 +2 -2

bet9 win 12 7 12/7 2 +2 0

bet 10 win 10 6 10/6 2 +2 +2

bet 11 loss 8 5 8/5 2 -2 0

bet 12 win 10 5 10/5 2 +2 +2

bet 13 loss 8 4 8/4 2 -2 0

bet 14 win 10 4 10/4 3 +3 +3

bet 16 loss 9 3 9/3 3 -3 -2

bet 17 win 12 3 12/3 4 •»-4 +2

bet 18 loss 8 2 8/2 4 -4 -2

bet 19 win 12 2 12/2 6 +6 +4

bet 20 win 6 1 6/1 6 +6 +10

This demonstration too proves the basic operability of DIVISION:

with 10 hits and 10 lost bets after 20 placed bets we see again a 10 unit gain

In order to keep bet sizes within a defensive limit we recommend two reductions

1. An attack should be aborted if a positive balance is achieved. During

the 2. demonstration that would be after the 10. placed bet. In Chat
case, the attack ends with a 2 unit gain. A new attack can be started
immediately, which begins again with Code 1 as 10 and Code 2 as 10.

2. An attack should be aborted likewise, when Code 2 falls below 3.

file:///C|/challenge2.1/Challenge21.htm (18 of 28) [12/3/2002 9:59:22 AM]

 INTRODUCTION

even when the total balance is stilt negative.

Both measures will keep the table bankroll in a reasonable limit and will
reduce the imponderability of the Zero-tax substantially.

In order to fully use the elasticity of a specific roulette strategy Code 2 should
not amount to under 10. A higher base value is quite possible,
however not over 20, since then an attack can drag on for a long time.
Code 1 can be defined variable, it should for the start amount to half
the value of Code 2. Thus with Code 2 beeng 20, Code 1 would be at least 10
That would be a very restrictive play with low starting bet sizes,
particularlv important if the probability of hits is rather small,
Offensive betting is possible, if the probability of a future hit accumulation
exists, for example after a lost session. In this case the Code 1 can be fixed on 28,Code
2 on 20.
An ideal relation for the beginning are identical Code numbers, for
example 20 / 20.
With each starting relation of Code numbers an extremely variable play with
outstanding gain perspectives is possible!
After introducing you with (.division" for even money bets,
we will now demonstrate the use of DIVISION with twelve number bets
Due to the pay out ratio of 2:1 on twelve number bets, DIVISION is
ideally suited for this kind of systems!
We start with Code 1 as 20 and Code 2 as 18, 18 corresponds to an
adequate score you can expect 9 hits with a 2 unit gain = total gain 18 units!
Once again we demonstrate the determination of bet sizes:

The two Code numbers are divided against each other ( 20 :18).
Results less 1 will be rounded up to 1. Results of the division starting from 1.5
are rounded up to 2 units, results between 2 and 2.4 are rounded down to 2,
from 2.5
rounded up to 3 and so forth-
Code 1 is increased after a loss bv the number of the lost units, it is
reduced after a hit by deduction of the amount of won units.
Code 2 remains unchanged after a toss and Is reduced after*
hit by 2 (pav out ratio of twelve number bets).

 INTRODUCTION

For succesful systematical betting with the roulette strategy

Challenge 2.1 it is essential that you keep strictly to all listed limits!
The 31 sessions played in August 1999 cover all limits. Every record
sheet
of these sessions contains an explanation of the limits used.

1. Game attack gain target :

minimum 1 unit, IF the first bet of a game is a hit you win 2
units (see session 1999-08-01) Sometimes when a game
begins with a couple of losses and the progression gets active
a game may even end with a 3 or 4 unit gain (see session
1999-08-06 and 1999-08-08)
2. Game length time
45 Ideal spins. (Ideal spins do not count the spins for Zero or
Double Zero)
3. Game Loss Limit
Minus 13 Units (see Session 1999-10-21)
4. Session Gain Target
5 Units in 45 ideal spins recommended 3 games/attacks

5. Session Stop Limits

if after 45 Ideal spins a session and a previous positive session
balance your last game is still negative, this last game and the
session as well are terminated.
(A) once the balance of you last game reaches a positive value
( see session 1999-08-02)
(B) The game limit of 45 Spins is reached (see Session 1999-
08-05)

maximum session length 64 spins

Challenge 2.1
Stop-Loss
Procedure

Approximately 50 % of the time you will reach the session goal of a 5 unit

 INTRODUCTION

gain in less
than 45 spins.
To maximize the profit, we recommend the following procedure:
Of your 5 unit gain you can use 2 units for further attacks. If the 2
units are lost,
you stop this new attack and keep the 3 units.
After a gain of 6,7, 8 or 9 units you do exactly the same: after the loss of 2
units you terminate the
attack.
After a gain of 10 units you terminate the attack after a loss of 3 units with plus 7.
After a gain of 11,12,13 Other 14 units you lose max. 4 units-Then the attack is
terminated.

If your total gain is more than 14 units, your maximum loss is restricted to 5 units.
y
With this Stop-Loss Procedure you can ride winning streaks
and avoid
losing streaks,
