Lost a tile, costume piece, or reflector? Here's how to figure out what's actually missing, what to replace first, and when a new base or kit makes more sense.
Quick answer
Replace the base or reflector first if the app won't recognize anything at all, because those two parts affect every game. If only one game is broken, replace just the missing playing pieces for that game instead of buying a whole new kit. For most families, the Osmo New Base & Reflector for iPad is the simplest single fix when the reflector is cracked, lost, or no longer clips on securely.
Losing a piece is normal in a house with kids. A Words tile rolls under the couch, a costume piece disappears into a toy bin, or the reflector gets knocked off the iPad one too many times. The trick is figuring out which part is actually gone before you buy anything.
The good news is that Osmo separates the parts that make the system run from the parts that make individual games work. Once you know which category your missing piece falls into, the replacement decision gets much simpler.
Start by testing what still works
Before you order anything, open one game and watch what happens. If the app launches but never sees your pieces, the problem is usually the base or reflector, not the tiles. If the app sees pieces fine but one specific game is unplayable, you are probably missing playing pieces for that game only.
Try a second game if you have one. A base or reflector problem will affect every game the same way, while a missing tile or costume piece only breaks the game that uses it. That one test tells you whether you need a system part or a game part.
- Wipe the reflector and camera area with a soft dry cloth before assuming something is broken.
- Restart the iPad and reopen the app once, since a frozen camera view can look like a missing piece.
- Check under couch cushions and inside storage bins before ordering a replacement.
When the missing part is the base or reflector
The base and reflector are the parts every game depends on. If the reflector is cracked, scratched, or lost, no app will read your pieces correctly. If the base is wobbly or the iPad no longer stands securely, that is also a system-level problem rather than a game-level one.
This is the situation where a base replacement makes sense. The Osmo New Base & Reflector for iPad is designed so you stand your iPad in the base, clip on the reflector, and play. Replacing both together avoids the frustration of a new base that still pairs with a damaged reflector.
- Replace the base and reflector as a pair if either one is damaged, since they work together.
- If you only need a stand and your reflector is fine, the Base for iPad is the lower-cost option.

When the missing part belongs to one game
Tiles, costume pieces, and similar playing pieces are game-specific. Losing one Words tile does not stop Creative Starter Kit from working, and a missing costume piece does not affect number games. In these cases you are replacing a game component, not the whole system.

If a single piece is gone and the rest of the set is intact, replacing that game's pieces is usually cheaper and faster than rebuying a kit. If most of the pieces for one game have scattered over the years, a fresh copy of that game may be the cleaner choice.
- Count what is left before ordering, so you know whether you need one piece or a full set.
- Keep small pieces in a labeled bag or bin between sessions to slow down future losses.
Choosing between a replacement part and a new kit
A replacement part wins when the rest of your setup is healthy and only one thing is missing. A new kit wins when several games are incomplete, when your base and reflector are both worn, or when your child has outgrown the games you own and you are ready for a different mix.
The Genius Family Starter Kit is built for households that want one package covering multiple ages, with 9 classic games and their hands-on playing pieces split across ages 3-5 and 6-10. If you are replacing scattered pieces across several games anyway, that kind of bundle can cost less than rebuilding game by game.
- Add up the cost of the individual replacements before defaulting to a full kit.
- If you already own a working base, you do not need to rebuy one with a new game.
How to avoid losing pieces again
Most losses happen in the ten minutes after a session ends, not during play. A simple end-of-session routine, where pieces go back into one container and the reflector comes off the iPad, prevents most of the problems parents write in about.
If your child tends to wander off mid-game, keep the play area small and consistent. Pieces that always live in the same tray are far easier to find than pieces that travel around the house.
- Store the reflector somewhere flat and dry rather than loose in a toy box.
- Do a quick piece count once a week if your child is in the habit of carrying pieces around.
Diagnosis: what's missing and what to do
- Symptom: no game recognizes any pieces: The base or reflector is the likely cause. Check that the reflector is clipped on straight and clean, then test a second app to confirm. If both apps fail the same way, replace the base and reflector rather than individual games.
- Symptom: one game is unplayable, others are fine: You are missing playing pieces for that specific game, such as Words Tiles or costume pieces. The base and reflector are working. Replace only that game's pieces. Do not buy a new base.
- Symptom: the reflector is cracked or won't stay clipped on: A damaged reflector degrades every game, even if it still looks usable. Cleaning will not fix physical damage. Replace the reflector. If the base is also worn, replace both together.
- Symptom: pieces are missing from three or more games: Rebuilding game by game usually costs more than a single bundle, especially if your child has also aged into harder content. Compare the total replacement cost against a multi-game kit before ordering parts.
- Stop here if the app itself is the problem: If pieces are present and the base is fine but the app still fails, the issue is software or setup, not a missing part. Do not buy replacements for a problem that is not physical.
Parts worth knowing about
- Osmo New Base & Reflector for iPad: To launch into the Osmo universe, just stand your iPad in this base, clip on the reflector and play. This is the single replacement that restores every game at once when the reflector or stand is the problem.
- Base for iPad: No catalog description was supplied for this item. It is the lower-cost stand option, but because no description is provided, confirm it fits your exact iPad model and your existing reflector before buying.
- Genius Words: Arrange physical Osmo Words Tiles to spell secret words, with each correct letter appearing on screen until the whole word is revealed. If your missing pieces are letter tiles, this is the game they belong to, so you know exactly what to replace.
- Little Genius Costume Pieces: Two hands-on games engage preschoolers in core subjects, and the Osmo base is required to play these games. Costume pieces only matter if you already have a working base, so fix the base first if both are missing.
Find out whether the missing part is system-level or game-level, and the replacement decision usually makes itself. Fix the base or reflector first if nothing works, replace single-game pieces if only one game is broken, and only step up to a bundle when the gaps are spread across several games.
