2017-09-29: v2.21 - Fixed two-tiering backwards compatibility issue that 2.20 exhibited when loading pre-v2.20 BCP files.

2017-09-28: v2.20
  • This version requires a new (free) license. Users were having issues with licenses becoming invalid occasionally, so this release should fix that.
  • Quicker startup and spawning of new windows.
  • Transaction logging: If you're unsure that you've set the options correctly, or want to put BonusChum through its places, then the new Transaction logging feature could be invaluable. A giant text log full of transactions (taken from numerous random sessions) takes place so you can verify what's happening.
  • SiD - Switch If Dipped (into bonus money). If you want to switch to Game 2 once you've dipped into bonus money, this is the new way to do it (setting the "Switch to Game 2" value to 1 x bonus amount to achieve the same thing is now deprecated). It is also now possible to combine this with setting the "Switch to Game 2" option to set two targets (one if your balance dip into bonus money, and one if your balance exceeds a specified amount).
  • Bug fix: Average wagering was misreported if the Bet Size Weight was not 100%. For two-tiering, reporting of average bets and average time (along with cash / hour) was also wrong if the Risk factors of both games were not the same.
  • Average wagering now takes coverplay into account. For extra clarity, maximum amounts are also now given for the Bets, time and wagering (approximated when two-tiering).

    2017-07-09: v2.17 - Updated signing of software certificate and now bonuses with a max cashout, where you have a second game switch point below the initial balance (switching game when you dip below a certain amount), and where you don't dip into bonus money, will now be treated as the max cashout not applying.

    2017-02-23: v2.16 - EV was miscalculated for sticky bonuses where the bet size was a large proportion of the deposit and only for games where you would need to redeposit (e.g: Blackjack or Casino/Texas Hold 'em). This error may be around 10% but could be as high as 50% or higher depending on settings.

    2017-01-28: v2.15 - Added colour coded 'save' button upon entering Notes. Fixed "Max session profit" stat with multiple threads. The "SGS" option has now turned to "LGS"; Instead of deciding whether to save all settings, or bonus-specific settings with a project, you now decide whether to load bonus-specific or all settings when OPENING a project. Other global settings such as threads, coverplay and the Risk plan are now included in the settings that are skipped when opening the project.

    2016-10-19: v2.14 - Disabling "Save bankroll with project" now also will skip saving surrounding bankroll options. Bug fix: Tier 1 bets in EWD scenarios do now not even partially dip into bonus money (affects big bets sizes in particular). Also added (semi-pointless but fun) 'Max session profit' stat.

    2016-10-09: v2.13 - More intelligent project saving and the file name is now visible in the main window. Added "New" button so you can easily clear the project and create new casino projects (without resetting all your bankroll settings etc.). Fixed calculation bugs in Early Withdraw scenarios involving large bet sizes or Max cashouts.

    2016-09-03: v2.12 - Added more two-tier stats and rejigged UI

    2016-08-02: v2.11 - Postwager second stage target isn't affected by the hidden final target setting in the Cashable section, and now also has a target of its own.

    2016-07-04: v2.10
  • Increased notes/paytable size by moving them to separate tab pages
  • Added Reload/Resave buttons
  • Added "Chance of Switch to game 2" statistic
  • Added "Cut profit" feature so you can share profits with someone else.

    2016-07-04: v2.05 - Postwager second stage now assumes a withdraw of the first stage before playing with the second stage bonus. Also less flickering and faster switch to main window after minimizing and reshowing.
    2016-06-19: v2.04 - Fixed crash involving changing cores and in relation to loading/saving projects
    2016-05-22: v2.02 - Fixed averaging of 'old-run' threads for current run using output.active var
    2016-05-20: v2.01 - Fixed GUI discrepancies involving second stage Postwager options

    2016-07-22 - VERSION 2
  • Multicore support!
  • Comprehensive coverplay feature added
  • For slots, you can now enter the number of lines. The risk level also now allows fine adjustment (not just 'low', 'medium', 'high', and 'very high').
  • Settings can now be loaded and saved as projects via dedicated buttons. This allows you to save a offers which you may repeatedly use in the future.
  • Added "Notes" section where you can write whatever you want.
  • Added "Early withdraw" for bonuses that allow you to withdraw even if you haven't completed wagering as long as you never went into bonus money.
  • Stealth mode added so you can change the icon to look like Notepad
  • Loading the program, and spawning a new window is now faster and more stable, not hiding away sometimes. Stop button is more responsive too.
  • Bet sizes can now optionally be a proportion of your balance rather than a fixed amount. This is useful for reaching targets more efficiently.
  • Added "Don't overshoot target/s" mode. This is used to reduce bet sizes when you'd otherwise exceed the target.
  • EV / bankruptcy is now corrected for cashbacks when wagering large proportions of the balance with 'mid-stake-bet-raise' games (e.g: Blackjack).

    More minor fixes:
  • Sample bankroll has been adjusted to allow for greater accuracy with postwagers or cashbacks where deposit amounts were very low or zero.
  • Allow bet size weight to exceed 100% for those very rare cases where casinos allow as such
  • Minor fixes where numbers appeared even when the corresponding control had been disabled or hidden.
  • Removed slightly misleading 'adjusted house edge' info for games such as Blackjack where the final bet size may not equal the initial bet size. Instead, refer to the adjusted Bet size weight (in blue) which is a truer representation of the game.
  • Although calculated correctly internally during simulation, the adjusted 'Bet size weight' in blue displayed an erroneous value if the house edge was adjusted from its original normal value. This is now fixed.
  • Added the 'Fixed' mode option to 'Wagering', 'Max cashout', 'Target', and 'Switch to game 2' dropdown menus
  • Deposits that are larger than the bankroll are now capped to the bankroll. This barely made any difference 99.9% of the time since deposits will tend to be small (<500) and bankrolls large (more than 5k), but it's useful for testing, and for a little extra accuracy sometimes.
  • New 'Relative' bankroll risk display mode helps you visualize risk more easily, especially for large bankrolls.
  • There's is only one Generic Slot paytable now. Variance/risk has been separated out into another field.


    2016-02-18: v1.86 - Fixed bug if cashback deposit was to zero, and the Cashback type was in Fixed mode.
    2016-02-14: v1.85 - Added partial bankroll gain stats (but only if Sample Bankroll is turned off)
    2016-02-11: v1.84 - Added gain rate to complement bust rate
    2016-02-09: v1.83 - Added support for switching to game 2 at a multiple of the deposit (rather than just the bonus)
    2016-01-29: v1.82 - Fixed problems when the Bonus is set to a fixed amount (rather than a percentage)
    2016-01-26: v1.81 - Bug fix - the max "Time (hr:m)" value was displayed incorrectly in v1.80. This is now fixed.
    2016-01-18: v1.80 - Countries which use the comma as a decimal point are now supported (fixes startup crash). Also, time output now uses hours+mins.
