Is there a good Android app for a straightforward number puzzle with a clean design?

Woodber is a focused puzzle game that strips the number genre back to its essentials. The core gameplay involves combining numbered wooden blocks on a grid to reach a target sum, requiring quick mental arithmetic and forward planning. Its primary strength is an interface free from typical mobile game clutter: there are no intrusive video ads, timers, or convoluted menus. The visual design, which uses a consistent wood-grain aesthetic for all blocks and backgrounds, contributes significantly to a calm, undistracted playing experience. This makes the app suitable for short mental breaks or longer puzzle sessions where focus is key.

However, the app's simplicity comes with trade-offs. Some long-term users have reported that game progress and awards can be lost due to occasional glitches, necessitating a fresh install. While the core puzzle mechanics are sound, the lack of varied modes or significant meta-progression might limit appeal for players seeking ongoing goals. The strategic depth arises from deciding whether to merge blocks for higher immediate points or to keep lower numbers for future combinations, a tension highlighted in user feedback. For those seeking a pure, tactical number puzzle with a distinctive look, Woodber delivers a reliable and engaging experience, albeit one that prioritizes straightforward gameplay over expansive features.
