We have shipped over 40 mobile titles in the last six years. Across all of them, the studios that struggled with monetisation shared the same handful of problems. None of them were about the core game being bad. They were structural: wrong timing, wrong pricing, wrong incentives. All fixable.

Here are the five we see most often, and exactly what to do about each one.

Mistake 1: Gating Too Early

Mistake 01
Showing the paywall before players are hooked

The most common mistake by far. Studios put IAP prompts in front of players who have not yet felt the core gameplay loop. If a player hasn't experienced the moment that makes your game compelling, they have zero motivation to spend. You are asking them to invest money in something they don't value yet.

✓ Fix Map your first moment of mastery, the point where a player feels genuinely skilled or invested. No monetisation should appear before this. For most casual games this is around session 3–5, not session 1.
💡
Rule of thumb: If a player hasn't completed at least 5–10 levels or 15 minutes of playtime, they are not yet a monetisation target. They are still an acquisition cost.

Mistake 2: Wrong IAP Pricing Tiers

Mistake 02
Offering only low-value or only premium packages

Players fall into rough spending segments: non-payers, minnows (£1–5/month), dolphins (£10–30/month), and whales (£50+/month). If your IAP store only offers a £0.99 coin pack and a £49.99 starter bundle, you are missing everyone in between: which is the majority of your actual paying audience.

✓ Fix Build a pricing ladder with at least 5–6 tiers: roughly £0.99, £2.99, £4.99, £9.99, £19.99, £49.99. Use a “best value” badge on your mid-tier to anchor spending behaviour toward your sweet spot.
“The goal of IAP pricing is not to maximise the revenue per transaction, it is to maximise the number of players who cross the payment threshold for the first time.” Internal LiveOps review, Nine Pixels, 2024

Mistake 3: Ad Placement That Punishes Players

Mistake 03
Interstitial ads at the worst possible moments

Showing a 30-second unskippable interstitial immediately after a player loses a level they have been trying to beat for ten minutes is a retention killer. It creates a Pavlovian association between frustration and your monetisation system. Players churn rather than spend.

✓ Fix Gate interstitials to positive moments: level completions, daily login bonuses, inventory full screens. Reserve the loss moment exclusively for rewarded ads (“Watch an ad to continue”), these convert at 3–8x the rate of forced interstitials in the same placement.

Rewarded vs interstitial: the numbers

In our experience across titles, rewarded video ads placed at the loss moment convert between 18–34% of eligible players. Interstitials placed at the same moment convert 0%, and cost you 4–12% of that session's DAU through churn. The math is clear.

⚠️
Never show more than one interstitial per session in the first two weeks after launch. Aggressive early ad frequency is one of the fastest ways to tank your Day 7 retention before your game has a chance to build an audience.

Mistake 4: No Soft Currency Sink

Mistake 04
Handing out currency with nowhere meaningful to spend it

Free soft currency (coins, gems, stars) has no value unless players have meaningful things to spend it on. When players accumulate thousands of a currency and feel no pull to spend it, the currency stops feeling valuable: and so does the premium version of it that you are trying to sell.

✓ Fix Design at least three currency sinks at different price points. At minimum: a cheap cosmetic, a mid-range gameplay boost, and a premium unlock that requires sustained play or a real purchase to acquire. Seasonal content works exceptionally well as a time-limited sink.

Mistake 5: Treating Every Player the Same

Mistake 05
One monetisation funnel for every segment

Showing your highest-LTV players the same £0.99 starter offer you show a new install is a significant missed opportunity. Whales do not respond to small-value offers, they respond to exclusivity, convenience, and status. Minnows respond to perceived bargains. Optimising for one segment hurts the other.

✓ Fix Segment by spend history after the first purchase. Players who have spent £10+ should see different offer surfaces than first-time payers. Most good mobile analytics platforms (GameAnalytics, Amplitude, Braze) support this out of the box.

The Common Thread

All five of these mistakes share the same root cause: building the monetisation system after the game is already done, rather than designing both together from the start. Monetisation is not a layer you add on top of a game. It is a design system that has to be woven into the core loop, the progression, and the social mechanics from day one.

If you are currently seeing ARPDAU below £0.04 on a casual title, or conversion rates below 2%, at least two of these mistakes are almost certainly in play. The good news is that all five are fixable without rebuilding the game: they are systems and placement decisions, not core mechanics.
