4charx compares welcome packs, starter bundles, free spins and promo codes from hundreds of mobile games — and adds up what every bonus is really worth.
Daily wheels, welcome spins and event jackpots explained. Try our interactive demo wheel and learn how to judge a free-spin bonus in seconds.
Double-reward weekends, login streaks, seasonal collabs and fresh promo codes — one calendar, with expiry dates and total values.
Flashing banners say “10× value”. We show what the bonus contains, what it costs and what it is worth in total.
We add up every item in a bonus — currency, spins, heroes, boosters, passes — using standard store prices, and show one clear number.
Each welcome pack is checked against the in-game store before publishing and re-checked whenever the publisher changes it.
Spin count, prize pool, odds, expiry and caps are listed side by side, so “50 free spins” actually means something.
No-purchase bonuses — login streaks, daily wheels, codes — always come before paid bundles.
See exactly when a bonus ends and whether it has returned before. No fake countdowns, ever.
All example prices are shown in pounds and can be switched to euros with automatic conversion in one tap.
4charx is an independent aggregator and review platform dedicated to one thing: bonuses in mobile games. Our editors collect welcome packages, starter bundles, free spins, wheel rewards, promo codes and seasonal events from across the market, then translate them into a single comparable number — the total bonus value.
We started with a simple frustration: the first screen of nearly every game shows a flashing “limited offer”, but nobody explains whether it is good. 4charx answers that question quickly and honestly.
Our editors install each game on fresh devices in several regions, record the starter flow and log every bonus shown during the first seven days. Each item inside a bonus is priced using the cheapest equivalent store purchase, then summed. The result is the total bonus value. Divide it by the price you pay and you get the value multiplier.
Some links on 4charx are affiliate or partner links: if you install a game or make a purchase through them, we may receive a commission at no extra cost to you. Partnerships never change a score, and every partnered listing is labelled. Read the full affiliate disclosure.
We publish our scoring formula, show the date each bonus was last verified, and correct mistakes openly. If a bonus turns out to be misleading, we say so — even when it comes from a partner.

* Total bonus value is our estimate based on standard store prices of each item. The multiplier is total bonus value ÷ cost. Contents and prices can change.
Demo only. No real prizes, no real money. Values are examples to show how wheel bonuses are priced.
Many mobile games hand out free spins on a wheel: daily, as part of a welcome pack, or during events. The prize is random, but the odds are not a mystery — in a fair game the prize list and the weighting are published or at least consistent.
Our demo wheel uses the weighted odds below. Notice that the big prizes are rare and the small ones common — that is exactly how most real wheels are balanced, and why a spin should be valued by its average prize, not by the jackpot.
Expected value of one demo spin: . This is the figure we use to price free spins in total bonus value.
Rule of thumb: value of free spins = number of spins × average prize value. If a game does not publish its prize odds, our editors estimate them from at least 200 recorded spins and note the sample size in the review.
