Fixed and Random Prize Games
1) Definition of formats
Fixed prizes - predefined amounts or multipliers that do not change from round to round. Example: winning X2 when hitting the right sector.
Random prizes - the size of the win is determined by a random number generator (RNG) at the time of the outcome, the range and probabilities may be known, but the result is unpredictable.
2) Fixed prize mechanics
Principle: the result of the event = winning by a previously known value.
An example in Tap & Win: a card labeled "+ 5 $" or "X3," which always gives this result when opened.
Impact on experience:
3) Random prize mechanics
Principle: the size of the winnings is selected from the range according to the probability distribution.
Example: open a cell in which can be like X1. 2, and X10, with corresponding odds.
Impact on experience:
4) Impact on RTP and probability
RTP is set at the level of the entire game, regardless of the prize format.
In fixed, RTP is implemented through the winning frequency.
In random - RTP is implemented by a combination of frequency and size of winnings.
Variance: in random higher, in fixed - lower with the same RTP.
5) Risk control and strategy selection
Fixed: better for players who prefer even pace, frequent small winnings and minimal drawdowns.
Accidental: suitable for those who are ready for increased volatility for potentially large payments.
Practice:
6) Application examples
Fixed: minigames with pre-prescribed rewards for winning a round; simple Tap & Win mechanics with the same X.
Random: "wheels of prizes" with different sectors, loot boxes with a range of awards, Tap & Win with dynamic multipliers.
7) Advantages and disadvantages
Fixed prizes
Ease of understanding.
Predicted bankroll behavior.
− Less gambling "peak" from unexpected winnings.
Random prizes
High emotional effect.
The possibility of rare big wins.
− Higher risk of rapid losses with a series of minimum payouts.
8) Choosing a format for the player's goals
For stability - fixed prizes, low volatility, control of the result.
For maximum excitement - random prizes, a high range of payments, rare "jackpot" moments.
It is optimal to alternate formats to balance emotions and risk.
Result
Fixed prizes give stability and predictability, random prizes give excitement and high variance. With the same RTP, the choice comes down to personal preferences: play for reliability or chase rare large winnings.

Impact on experience:
- Transparency - the player knows what he will get if successful.
- Predictable variance: Stable win values smooth out bankroll fluctuations.
- − Less emotional "surprise" than in random formats.
3) Random prize mechanics
Principle: the size of the winnings is selected from the range according to the probability distribution.
Example: open a cell in which can be like X1. 2, and X10, with corresponding odds.
Impact on experience:
- Surprise effect - each round can give a unique result.
- Possibility of large factors with luck.
- − Above variance: bankroll is subject to rapid fluctuations.

Accidental: suitable for those who are ready for increased volatility for potentially large payments.
Practice:
- In random formats, use bankroll management with lower rates.
- In fixed, you can afford a higher rate at the same level of risk.
