Challenges
This is the only place you can take on a challenge. Nothing is ever suggested to you on another screen, there is no recommended-for-you list, and no notification invites you to join one.
Group 1 · Taking a break
Seven days without a bet
Reward: the “Seven clear days” badge · 41% of people who start it finish it Estimate
Progress counts in days. There is no countdown.
Taking a breakThirty days without a bet
Reward: the “One month” badge and profile title · 12% of people who start it finish it Estimate
This one is hard. The 12% is printed up front so you know what you are taking on.
Taking a breakOne weekend without opening the betting screen
Reward: the “One clear weekend” badge · 74% of people who start it finish it Estimate
The easiest tier, and a good place to start.
A break challenge pays a badge, never tokens. A badge cannot be turned into tokens and there is nothing you can stake with one — stopping for a week is not a way to build up a bankroll for the next one.
Group 2 · Long betting runs
Fifty bets in a row
Target win rate 55% · reward: a badge and a house edge comparison report · 15% are estimated to reach it Estimate
It ends automatically at 50 bets, win or lose.
Long betting runOne hundred bets in a row
Target win rate 65% · reward: a badge and a house edge comparison report · 0.034% are estimated to reach it Estimate
More bets tend to stabilise the win rate near the modelled normalised win probability, while the average token return tends towards the separate negative edge. That distinction is the lesson.
Every figure on this page carries an Estimate label because nobody has finished one of these yet. The 50-bet figure comes from a 10,000-run simulation; the 100-bet figure is the exact binomial estimate at the expected win rate of 47.6%. The break figures are hard-coded until there is enough real data. Each one is replaced by the observed rate, with the sample size beside it, as soon as there is one.
The challenge list is fixed and published in full. tibbi never generates a personalised challenge based on your behaviour.
Challenge rewards sit outside the token economy: no challenge pays tokens, and no badge or title can be converted into them. New tokens come only from completed lessons and fixed Showdown milestones.
Tokens have no cash value. They cannot be bought, sold or exchanged for money.
