An independent guide to CM889
CM889 is the queried name discussed here. This guide has not established an outside operator, licence, official address, app or payment service for that name. A domain or search position cannot establish an official identity. The demo on this page is this guide’s own simulation and does not certify or reproduce an outside product.
Two reels and the reward score
Each reel independently chooses one symbol from 0–9 and A–F with equal probability; A–F have values 10–15. Read n = 16 × first reel + second reel + 1. This makes n uniform from 1 to 256. Count its odd positive divisors, including 1, then subtract 1 to obtain the reward score. The score can be zero.
Three curves and the gross multiplier
Before spinning, choose linear, squared or cubed weights. For score s, these weights are s, s² and s³. Their totals over 256 integers are 565, 1889 and 8239; each mean is its total divided by 256. Gross multiplier = 0.96 × 256 × weight / the relevant total. Raw gross return is the captured stake times this multiplier; it is not net profit. All three modes have exact expected gross RTP 24/25, or 96%. This is neither the win probability nor a promised session result.
A worked example with integer 12
Symbols [0, B] give n = 12. Its odd positive divisors are 1 and 3, so the statistic is 2 and the reward score is 1. The linear multiplier is 6144/14125, approximately 0.434973. At stake 20 with no saved carry, raw gross return is approximately 8.69947: the wallet receives 8 whole coins and stores about 0.69947 as carry. A starting balance of 1,000 becomes 988, so this return still leaves a loss of 12 whole coins. Symbols [0, 0] give n = 1, score zero and zero return in every mode.
Stakes and active-round controls
Select a stake of 10, 20, 50 or 100 virtual coins; the default is 20. Each round captures one stake and its selected curve. The stake is deducted when spinning starts. Stake buttons, curve buttons, restoration and another spin are disabled during the animation; sound remains available. The spin button is disabled if the balance cannot cover the selected stake. There are no row bets, bonuses or interim collections.
Whole coins and fractional carry
At settlement, raw gross return is added to saved carry, the whole part is credited to the wallet and the remainder is saved. The result message names whole coins actually credited, rather than unrounded gross return. A positive return below one coin may credit no whole coin while increasing carry. A zero-return round leaves existing carry unchanged. Carry persists in localStorage across settlement, restoration and reload.
Frequently asked questions
Does this page verify an official CM889 service?
No. This guide has not established an outside operator, licence or official address. Its demo is its own independent simulation.
How is the reward score calculated?
Read n = 16 × first reel + second reel + 1, count its odd positive divisors and subtract 1. Choose a linear, squared or cubed weight before spinning.
Does 96% RTP promise 96% back in a session?
No. It is the exact expected gross return across the distribution, not win probability or a session guarantee. Gross return is also different from net profit after deducting the stake.
