Crossmath Challenge
Place numbered tiles into a crossword-style grid so every horizontal and vertical equation works, hints included.
On a phone, turn it sideways after tapping Play, then use fullscreen for a larger play area.
Loads the game from gamemonetize after you choose Play. Nothing loads before that.

What we found
Playable and honest: the Play gate deferred all third-party loading until clicked, one skippable GameMonetize preroll preceded gameplay, and tile placement, Hint, Undo, Check feedback, audio toggles, and fullscreen entry/exit all worked in desktop and mobile sessions. We corrected our difficulty estimate from Hard to Medium after seeing the game's own selector default to Medium.
Mobile: Tested at phone size: portrait reflows to a single column and shows Snacko's 'turn it sideways and use fullscreen' callout; the 16:9 game frame is small in portrait but starts and renders. Landscape 844x390 gives a much larger board and a Hint tap registered immediately.
Ads and interruptions: One skippable GameMonetize preroll video ad played after the game-internal Play on first launch (Skip Ad control, 'Powered by GameMonetize' branding under the frame). Later restarts in the same session started without a new ad. The Snacko page itself shows no ads.
Tips from our playtest
- Fill one-blank equations first: in our Stage 1 both 5 + ? = 15 and 5 x ? = 30 had exactly one tray tile that fit.
- Check is free while the grid is incomplete - it says 'Keep going, not all tiles placed yet.' and costs no heart.
- Hints are limited (three on Medium) and Undo hands the tile back but does not refund a spent hint.
- Tap a tray tile, then tap the cell - the two-tap flow placed every tile correctly in our run.
- On a phone, play sideways with fullscreen; the portrait frame squeezes the board until the tiles are tiny.
Questions about this game
- Is Crossmath Challenge free?
- Yes. It runs in the browser on Snacko Games with no account, and the provider plays one skippable ad when you start a session.
- How hard is it?
- The game's own selector defaults to Medium with Easy and Hard presets. Stage 1 on Medium stayed relaxed: single-blank equations, three hints, and three lives.
- Does it work on a phone?
- Yes, in both orientations. Sideways with fullscreen is much more comfortable; in portrait the 16:9 board gets small, which is why the page suggests rotating.
- Can I take back a move?
- Yes - the Undo button returns the last placed tile to the tray, but it does not refund a spent hint.
