RNG-based training is available on Pro and Elite plans.

What is RNG in poker training?

Many solver ranges include mixed strategies — hands where the correct play is to take different actions at different frequencies. For example, a solver might say to raise AJo 65% of the time and call 35%. At the actual poker table, you’d use a randomization method (like checking the second hand on a clock or using a mental number) to decide which action to take. RangeSharp’s RNG (Random Number Generator) simulates this process during training.

​
How it works

When RNG is enabled and you’re dealt a mixed-strategy hand:
  1. RangeSharp generates a random number between 0 and 100.
  2. The RNG bar displays this number visually.
  3. You check where the number falls relative to the action frequencies.
  4. You choose the action that corresponds to that range on the RNG bar.

​
Example

Suppose AJo has these frequencies: Raise 65%, Call 35%.
  • Random number is 42 → Falls in the Raise zone (0–65) → Correct answer is Raise
  • Random number is 78 → Falls in the Call zone (66–100) → Correct answer is Call

​
The RNG bar

The RNG bar appears during training when you’re dealt a mixed-strategy hand. It shows:
  • A horizontal bar divided into colored segments, one per action
  • The segments are sized proportionally to the action frequencies
  • A marker showing where the random number falls
  • The number itself displayed above the marker

​
Enabling RNG

​
In a study plan

  1. Open or edit a study plan.
  2. Toggle RNG Enabled to on.
  3. Mixed-strategy hands will now use the RNG during training.

​
In training preferences

  1. Go to Settings → Preferences.
  2. Under Training, toggle RNG settings.
  3. You can also configure the RNG bar orientation (horizontal/vertical).

​
Training without RNG

When RNG is disabled, mixed-strategy hands accept any of the valid actions as correct. If a hand is 65% Raise / 35% Call, answering either Raise or Call is marked as correct. This is useful when you’re still learning the basic range and don’t want to worry about frequency precision yet.

​
Tips

Learn the range first, then add RNG. Master which hands belong to each action in Decision mode without RNG. Once you’re consistently accurate, enable RNG to practice frequency-correct play.
  • Start without RNG to build confidence
  • Enable RNG once you’re scoring above 80% accuracy
  • Pay attention to the threshold numbers — knowing that AJo switches at 65 is a useful mental anchor for real play
